Gutenberg: & converts to & in page title

[xpurichan]

Steps to reproduce

1. Use any WPcom simple site
2. Create a new page/post and write a page title, use the & symbol in the page title
3. Publish the page
4. Note how & is converted & in the editor as shown here:
   

(Note that & still appears normally on the actual website, it only appears as & in the editor from the moment the page is published.)

I was only able to replicate this on simple sites, and I believe it's related to the recent Gutenberg update. I couldn't replicate on an Atomic site even after I updated Gutenberg to version 7.8.0

What I expected

& should display as itself

What happened instead

& should not be converted to &

Browser / OS version

N/A

Context / Source

Found while I was testing some issues with the Media & Text block, not user reported.

Title migration for all sites wasn't finished when we upgraded, hence these popping up when customers open editors for non-migrated sites.

This should get fixed on its own as the migration script progresses (could already be done for this site).

I think this particular one is an ongoing issue that needs to be resolved in Gutenberg (getting the editor to decode expected encoded entities created by users that don't have the unfiltered_html capability). It's logged upstream here: WordPress/gutenberg#20490

Thanks @arunsathiya ! I'd searched but somehow missed this one anyhow.

As mentioned above, this is logged upstream here: WordPress/gutenberg#20490. Closing.

This seems to be still an issue on simple sites, not just with "&" but with other characters too.

Simple site mrfoxtestingsite.wordpress.com:

I did a quick test on a AT and on self-hosted sites and it works fine there.

Self-hosted (local, with and without the Gutenberg plugin):

Atomic (with and without the Gutenberg plugin) mystoreadminpractice.blog:

I am going to reopen this issue and move it to the triaging board

I was able to replicate. @dpasque, pinging to get your attention!

If this issue was closed for a year already, this is likely a new occurrence of the same problem? @WunderBart @fullofcaffeine can this be due Gutenberg upgrade?

[dpasque]

Tagging @Automattic/flow-patrol-create based on issue content. Will also ping internally.

I was not able to reproduce this on a newly created simple site:

@mrfoxtalbot , is the issue still happening for you?

[mrfoxtalbot]

Thank you for checking @mreishus. I am no longer able to reproduce the issue on a simple site. I'm marking this as solved.
