Gutenberg 18.9.0+ - Editor hangs / fails to load while Gutenberg is activated #93395

Open masperber opened 3 months ago

Quick summary

After Gutenberg 18.9.0 was pushed to WoA, some customers are reporting that the editor hangs/fails to load when trying to create or modify a page or post.

I haven't been able to reproduce the issue on my end, but the 2 customers who reported it noted that the editor was hanging consistently, and then the issue was resolved when Gutenberg was deactivated. I noted a short delay for the editor to load, during which I noted this error in the console:

chromewebdata/:1 Refused to display '{domain}' in a frame because it set 'X-Frame-Options' to 'deny'.

This issue was escalated and intermittently reproduced by @obenland. Discussion here: p1723150860104919-slack-C02FMH4G8

Steps to reproduce

  1. Ensure Gutenberg 18.9.0 is activated on a WoA site
  2. Attempt to create or modify a page or post
