This function will either correct the position passed in,
|
|
or leave the position unchanged.
|
|
|
|
When the (first) item to insert is a block level element,
|
|
and our insertion position is after the last visible item in a line,
|
|
i.e. the insertion position is just before a visible line break <br>,
|
|
we want to skip to the position just after the line break (see bug 68767)
|
|
|
|
However, our logic to detect whether we should skip or not
|
|
needs to be more clever.
|
|
We must not skip when the caret appears to be positioned at the beginning
|
|
of a block, in that case skipping the <br> would not insert the <br>
|
|
at the caret position, but after the current empty line.
|
|
|
|
So we have several cases to test:
|
|
|
|
1) We only ever want to skip, if the next visible thing after the current position is a break
|
|
|
|
2) We do not want to skip if there is no previous visible thing at all
|
|
That is detected if the call to PriorVisibleNode gives us an offset of zero.
|
|
Because PriorVisibleNode always positions after the prior node, we would
|
|
see an offset > 0, if there were a prior node.
|
|
|
|
3) We do not want to skip, if both the next and the previous visible things are breaks.
|
|
|
|
4) We do not want to skip if the previous visible thing is in a different block
|
|
than the insertion position.
