The test as a whole has been added just 14 days ago and the intermittent seems to be quite rare, so I would rather think, that the test has (or reveals) a problem that is independent from the backfill range? Maybe Yulia has an idea if it is worth to have a look here.

I didn't account for dynamic imports being potentially reordered, which appears to be possible. This
seems to have lead to the intermittent. This updates the two affected tests.

Taking as Yulia will be on leave.

Set release status flags based on info from the regressing bug 1540913

The loading of dynamicImport_immediate.mjs sometimes takes longer than
the other module scripts and causes intermittent failures, since it
doesn't have dependencies on the other module scripts so we just simply
remove it.
