Comment 34

[Daniel Holbert [:dholbert]]

This test is annotated as random [PASS, FAIL] on a bunch of configurations; really, it's probably random everywhere, and we just didn't cover all of the configurations.

Looking at the test, I think it needs reftest-wait. The reftest snapshot looks like it's been taken before the dynamic JS tweak has taken effect. reftest-wait would address this and hopefully make the test pass reliably, which would let us remove the .ini annotation file altogether.

Comment 35

[Daniel Holbert [:dholbert]]

Attachment: Bug 1659430: Add "reftest-wait" to WPT increase-prev-sibling-height.html, to address intermittent failures. r?#layout-reviewers

This test has some JS that restyles an element, and the test implicitly expects
this JS to run before the screenshot is taken (otherwise the test fails).

However: before this patch, I don't think there's anything stopping the
test-harness from taking its screenshot earlier -- the screenshot can happen as
soon as the load event fires (and after any pending paints at that point are
flushed). This may be before the test's requestAnimationFrame-triggered JS has
been run.

This patch addresses this issue by adding 'reftest-wait', which explicitly
requires the test harness to delay its screenshot until after the restyle has
occurred.
