[Maire Reavy [:mreavy]]

Hi Sean, Can you ask someone to look into why this increased in frequency?  Thanks.

Comment 18

[Sean Voisen (:svoisen)]

Ting-Yu, any insight here? It's in multicol so hopefully you are familiar.

Comment 19

[Ting-Yu Lin [:TYLin] (PST, UTC-8)]

The initial observation is that testing/web-platform/tests/css/css-multicol/zero-column-width-layout.html renders *very* slowly (takes a few seconds) when I open it in my local debug build. I won't be surprised if it is timeout on CI's debug builds.

Comment 20

[Ting-Yu Lin [:TYLin] (PST, UTC-8)]

In testing/web-platform/tests/css/css-multicol/zero-column-width-layout.html, there's "column-width: 0", so ChooseColumnStrategy() decides that the column's isize (colISize) should be "1 app unit" at [1], and it ends up creating 1000 columns (it reaches kMaxColumnCount [2]). Then these 1000 columns need to be reflowed again and again to find the best balance height. That's why it's super slow.

I think we might be able to follow the spec [3], which says "Used values will be clamped to a minimum of 1px." to reduce the number of columns we created in this test case.

[Ryan VanderMeulen [:RyanVM]]

Is this worth backporting to 62 or can it just ride the trains?

Comment 28

[Ting-Yu Lin [:TYLin] (PST, UTC-8)]

This fixed a minor edge case of column layout. I think it can just ride the trains.
