Changing fonts in site editor causes blocks to break

[brittanygray902]

Quick summary

User has the theme Twenty Twenty-Three

When changing font for blocks the block is broken and shows error message.

"This block contains unexpected or invalid content. Attempt Block Recovery."

Steps to reproduce

(Could not reproduce on my own test site)

Steps to reproduce:

Set theme: Twenty Twenty -three

1. Open Site Editor
2. Select block > Change font (Playfair Display seems to break blocks every time so I'd try this one)

What you expected to happen

When changing the fonts you expect the font to change / apply, with no errors.

What actually happened

When changing fonts on a test site I did not see the same error message come up.

However, on the user's site they continue to get the error when changing fonts - specifically they notice this when changing to the font Playfair Display.

The error message is removed and blocks display / function properly when the default font is set back.

I can replicate this on my Simple test site, and I am very confident that it is specific to when a font is applied to a block that sits inside a parent block which allows nested blocks, e.g. group or column block.

I was testing it out before I found this GH report - here's my recording:

I just tested again and I found that this workaround can help:

1. Ensure paragraph block does not have a custom font
2. Set font on its parent container instead
3. Save, refresh
4. No error.

I am seeing this on my personal site too. I have multiple Paragraph Blocks inside a Group Block and each of them has a Custom Font added through the default Paragraph Block Settings. They all have the Attempt Block Recovery error.

I am getting the same on the Timeline Block when I have Paragraph Blocks with a custom font inside the Timeline Entries.

I have multiple fonts in the container which is why the above workaround doesn't work.

Clicking Attempt Block Recovery gets rid of the notice until the next time I open the editor. Clicking Resolve instead of Attempt Block Recovery just strips the Block of all the customizations, which isn't ideal.

The problems reported in this issue are not reproducible anymore. The editor is working as expected, following the reproduction steps mentioned here, so I'm closing the issue. I've included below a screencast of the testing in Simple sites.

Hi @matiasbenedetto, I think you need to refresh the editor to see the error. I am still experiencing it:

Hi @eoinsav, I refreshed the site several times, and I wasn't able to reproduce it.
