Layout test imported/blink/svg/as-image/image-change-with-equal-sizes.html is flaky. Example image diff: https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20(Tests)/r229070%20(5640)/imported/blink/svg/as-image/image-change-with-equal-sizes-diffs.html Note that the bottom of the 'g' character sometimes gets cut off, but not always.
(But the green squares really are always the same size, which is good.)
The test or tests filed under this bug are not failing anymore. Test expectations updated in https://commits.webkit.org/258724@main.
