Browser window frozen when mentioning user not in channel.

[gelpiu-developers]

Description:

We are 15 people using Rocket.Chat and all but one computer are experiencing problems when mentioning users not in the channel. The one computer where is working is significantly more powerful than the others (Macbook Pro M3 vs Windows AMD Ryzen 5 5500U With Raden Graphics 2,10GHz 8GB/Macbook Air).

In the computer where it works, after sending the mentioning message, the dialog offering the after-mention actions is shown. In the other computers, the browser window just gets frozen, and you have to close it to be able to work again.

We have test with different browsers and the behaviour is the same. We have test using different users in different computers and with different roles and it just won't make a difference. It is always working in the more powerful computer and not in the others.

Steps to reproduce:

1. Enter public channel
2. Mention user not in the channel.
3. Browser window gets frozen.

Expected behavior:

1. Enter public channel
2. Mention user not in the channel.
3. Dialog selection mention options appear.

Actual behavior:

Browser window gets frozen.
