In the printing preview, we create continuous table frame if table is too
long to containing in a page. But the default value of
NeedToCalcHasBCBorders is false which means we don't calculate
HasBCBorders for continuous table frame. Thus, the border collapse is
not shown when printing preview.

The old code doesn't work because mScriptHandlingObject is a nsWeakPtr,
which cannot be casted to nsPIDOMWindowInner directly.
Since scriptHandlingObject is a strong reference to the same object, we
can just try casting that.

Expose the API to get/set inherited scale from stacking context and we can
use these APIs to calculate correct scale for OMTA

Multi-color shadow is not allowed in spec. We could use the same color
of the text as the color of the decoration line when we paint the
shadow.

Doing it off a runnable makes the flattened tree inconsistent until that
runnable runs.
Also add an assert in frame construction that would've caught the first
only-unbind patch.

There are two callers of nsFilterInstance::PaintFilteredFrame:
1. nsSVGUtils::PaintFrameWithEffects at [1]
This function is used while painting a filtered element on a path which
display item painting is not supported yet, such as drawing elements inside a
indirect painted SVG object, such as a mask, a clipPath or a gradient object.
Let's say we have a masked element, which refers to an SVG mask, and there is
a filtered element inside that SVG mask.
Using nsFilterInstance::PaintFilteredFrame to paint that filtered frame in
the mask, we have to pass a gfxContext and a transform matrix to it. The
transform of the gfxContext 'target' that we pass in consists of a transform
from the referenced frame, of the masked frame, to the masked frame. We also
pass in a transform matrix 'aTransform', this matrix contains a transform
from the the masked frame to the filtered frame in *device units*, which
means it contains css-to-dev-px scaling factor.
2. nsSVGIntegrationUtils::PaintFilter at [2]
This function is used by normal display item painting.
The same, we pass a gfxContext 'context' and a transform matrix 'tm' into
nsFilterInstance::PaintFilteredFrame. The transform matrix of 'context'
consists of a transform from the referenced frame, of the filtered frame,
to this filtered frame, but the scale factor was taken out . The transform
matrix 'tm' we pass in contains scale transform from the referenced frame to
the filtered frame in *device unit*.
Inside nsFilterInstance::PaintFilteredFrame, we treat the transform matrix of
'aCtx' and 'aTransform' as parameters we pass in in #2 caller. So it can be
failed in #1. For example, if the filtered frame inside a masked frame has a
translation transform applied, since that translation was put in 'aTransfrom',
but we only use the scale factor of 'aTransform' in
nsFilterInstance::PaintFilteredFrame, translation factor disappears.
In this patch, I unified the definition of parameters of
nsFilterInstance::PaintFilteredFrame:
1. nsFilterInstance::PaintFilteredFrame(aCtx): the transform matrix of aCtx
should be a transform from the referenced frame to the filtered frame in
*css units*. Originally, the aCtx we passed in #1 is in device units, which
should be fixed; the aCtx we passed in #2 does not even include css scaling
factor, need be fixed too.
2. nsFilterInstance::PaintFilteredFrame(aTransform): this transform matrix
should contain only scaling factor in device units. And I removed it in the
end since I found we can get this value easily right inside the callee.

I noticed this error message on fixing dom/workers/test/test_suspend.html:
WARNING: NS_ENSURE_TRUE(mDocViewer) failed:
file layout/base/nsDocumentViewer.cpp, line 3863
It happens when a nsDocumentViewer::Close() is followed by a
nsDocumentViewer::Open(), the viewer would have been disconnected. Since it
takes only one-line change to fix I just include it in this bug.
