Fixes ByteLengthQueuingStrategy.size WPTs that were previously marked as TIMEOUT/CRASH #40890

Taym95 · 2025-11-25T22:48:36Z

I got trigged by this:

Servo is the only one TIMEOUT on this test, but we don't have a tests/wpt/meta/streams/queuing-strategies.any.js.ini, when I run it locally I get one test TIMEOUT and another one CRASH, this should fix it.

Before this fix:

[queuing-strategies.any.worker.html]
  expected: CRASH

[queuing-strategies.any.html]
  expected: TIMEOUT
  [ByteLengthQueuingStrategy: size behaves as expected with strange arguments]
    expected: TIMEOUT

… as TIMEOUT-CRASH Signed-off-by: Taym Haddadi <haddadi.taym@gmail.com>
