Fixes #19033
This pull request seeks to improve stability of the embedding end-to-end test suite. See #19033 for complete debugging details.
The changes here operate on the assumption that there is a race condition between embed resizing and the behavior of Puppeteer's
page.clickto bring the block appender into view between adding embeds.The goal of these changes is to change from:
Before: Add all blocks, then validate the results.
After: Validate the result of an embed insertion before proceeding to add the next.
The idea with this is that, by performing the validation using
waitForSelector, we can have a higher confidence that the embed preview is rendered in its final state, and won't be subject to further resizing.Testing Instructions:
Build should pass.
Ensure end-to-end tests pass:
