Bug 1457476 [wpt PR 10685] - Add tests for floats next to new formatting contexts., a=testonly

Browse Source 
Automatic update from web-platform-testsAdd tests for floats next to new formatting contexts.

Whether an in-flow block-level box that establishes a new formatting
context fits beside a float or not determines whether the float is
adjoining with the new formatting context box or not.

This matters if the box that establishes a new formatting context has a
top margin. If the float turns out to be adjoining, it's affected by
that margin, but not otherwise, i.e. if the new formatting context box
needs to go below the float due to insufficient available width.
