Bug 1749414 [wpt PR 32319] - Fix modal-dialog-scroll-height.html, a=t…

…estonly

Automatic update from web-platform-tests
Fix modal-dialog-scroll-height.html

This test is failing in all browsers on wpt.fyi due to the hard coded
height:
https://wpt.fyi/results/html/semantics/interactive-elements/the-dialog-element/modal-dialog-scroll-height.html

I'm not sure why it passes in the chromium test infrastructure, but
people want to remove it:
web-platform-tests/interop#12 (comment)

This patch replaces the hard coded height with window.innerHeight.
