Disable BlockPreviews from axe-core tests.

[Addison-Stavlo]

Description

Hopes to resolve e2e test failures from the error "Failed to inject axe-core into frame (about:blank)" by disabling BlockPreviews from axe tests. This seems to make sense as Block Previews are disabled from interaction and are used as images, so they should not make sense for a11y tests in the first place.

How has this been tested?

Unfortunately it failed on the last run with the Failed to inject axe-core into frame (about:blank) error. It seems like a few folks have run into this on the axe repos:

• Failed to inject axe-core into frame dequelabs/axe-puppeteer#25
• puppeteer: failed to inject axe-core into frame dequelabs/axe-core-npm#98

Unfortunately both issues are currently closed.

[talldan]

I tried a different way on #26535.

Unfortunately it failed on the last run with the Failed to inject axe-core into frame (about:blank) error.

I wonder if giving the selector for the content instead of the container changes anything. Running this out of curiousity.

Great! I like where that one is going, good catch with the undocumented disableFrame function.

[Addison-Stavlo]

The template-parts test has passed 3x in a row after a7945f7 . I wonder if this would make sense as an alternative (or addition) to what is being done in #26535.

[talldan]

Awesome, let's go with this as it's much simpler than #26535.

[gziolo]

It still doesn't resolve the issue fully:

[Addison-Stavlo]

It still doesn't resolve the issue fully:

Oof.. the intermittency is a killer. Should we revert this?

[gziolo]

It feels like it helped a bit do it's fine to keep it until there's a better fix discovered.

[talldan]

I'll revisit #26535.
