This appears to be limited to Mac-wk1.

Marked test as flaky in https://trac.webkit.org/r227706

This test is still flakey. It is now flakey on Release builds as well. Additionally it is flakey on iOS 11 Debug wk2. 

The issue still seems to be those two extra blank lines in the output

[Alexey Proskuryakov]

The test itself is buggy - it starts checks on a zero timeout, but there is no guarantee that WebKit has already parsed </html> by that time. At the very least, it needs to use onload.

But I'm not sure if we care about imported/blink tests enough to fix them. Maybe just delete, or WontFix in TestExpectations.

Adjusted test expectations in https://trac.webkit.org/changeset/234695/webkit

[ macOS wk2 ] imported/blink/fast/text/international-iteration-simple-text.html is a flaky failure

Description:
imported/blink/fast/text/international-iteration-simple-text.html

The test is now affecting macOS wk2.

This new behaviors' first failure that I saw on the dashboard was 3/29/2022 at r292081, but this was to fix a build break and does not appear relevant to causing this issue.  This test seems to have been flaky since the start.

I have marked this test as a flaky failure while this issue is investigated.
