Unread message bug when topic contains numbers in parentheses

[amative1]

Describe the bug

When using the App (both PC and Mac), any topic containing a positive number in parentheses is treated as an unread count.

To Reproduce

Create a thread with (10) in the topic title, server icon and app icon display 10 unread messages (even if less than 10 messages exist on the server

Expected behavior

Unread message count should not show 10 if topic contains (10)

Screenshots

Desktop (please complete the following information):

App: Zulip 5.8.1
Electron: 13.1.7 (Node v14.16.0)
Operating System: darwin x64 20.6.0

Was also tested by a separate user on a Windows PC

May be linked to #1034 but unsure as no context was mentioned

This is weird. But I am unable to reproduce it in Windows 11 and I no longer have a mac.'

[amative1]

Does it still only show 2 unread when you click on (10) test 1 to view that thread specifically (it looks as though you're viewing #test here instead

[manavmehta]

Yes, if I view any opened stream/threads, it shows 2 still. The actual unread count.
@timabbott could you reproduce this?
I'll try reproducing for a custom zulipchat org.

[timabbott]

I don't have a mac but perhaps @alya can try reproducing on one.

[alya]

I can't replicate, sorry.

[amative1]

More data: I was able to replicate my bug in the Zulip Community server, in the existing (10) test 3 (10) and New Topic (2021) threads from the screenshot above.
