<!--
Need an svg element that references a clippath that is display none ( so that we don ' t use the clip path ) .
Then make the clippath no longer display none ( and do it without touching the clippath itself , ie make an
ancestor no longer display none ) .
We should now draw the clip path , but the bug made us not invalidate .
Then we can make things worse using retained display list partial updates by marking a frame modified
that is affected by the clip path a couple times . The retained display list won ' t have the nsDisplayMask
container , but the modified display list will have the nsDisplayMask , this will confuse merging when the
same item appears inside two different containers .
Note that we image . testing . decode - sync . enabled = false for this test because sync decoding triggers extra
invalidation which " fixes " this bug before it gets a chance to appear . Bug 1866411 tracks this .
