Renaming custom emojis breaks image

[EnCz]

Description:

After renaming an emoji the image is still visible in Administration but in chat only a little question mark appears.

Steps to reproduce:

1. Go to 'Custom Emojis' in Administration
2. Create new emoji with name 'foo'
3. Write ':foo:' in chat -> Emoji shows
4. Go to 'Custom Emojis' in Administration and change name to 'bar'
5. Write ':bar:' in chat

Expected behavior:

Emoji shows

Actual behavior:

Little question mark placeholder shows

Additional context

If I upload the image again when renaming and then save the emoji it works as intended.

This maybe is a fundamental problem in Administration and related to: https://github.com/RocketChat/Rocket.Chat/issues/18441 https://github.com/RocketChat/Rocket.Chat/issues/18458 https://github.com/RocketChat/Rocket.Chat/issues/18493

This is still a bug in 3.7.0.

Renaming an emoji breaks previous use and new use of the emoji.

(They show a white "?" in a black square).

Today I investigated into several problems regarding custom emojis (cf. https://github.com/RocketChat/feature-requests/issues/807, https://github.com/RocketChat/Rocket.Chat/issues/26980).

In that process, I stumbled upon the problem described in this issue as well which still persists in Rocket.Chat 5.1.4:
