  [IFC][Ruby] Fix adjacent base/annotation overhang
https://bugs.webkit.org/show_bug.cgi?id=263806

Reviewed by Antti Koivisto.

Overhanging pulls content from right to left (changes visual geometry) and in case of multiple (adjacent) base/annotation pairs
we have to have up-to-date geometry all the way to be able to do overlap checking. We can either do it
by passing in the accumulated shift to overlap checking functions (rather cumbersome) or update
the geometry for all subsequent display boxes before running the overlap test (see FIXME).
