Repo Topic Containing Backslash Leads to Javascript Error

[kdumontnu]

Description

If you create a repo topic with a backslash you receive the following javascript error:

Error: Syntax error, unrecognized expression: [data-value="test\"]
    at Ha.error (jquery.js:1487:8)
    at Tu (jquery.js:2153:8)
    at Cc (jquery.js:2578:12)

It's unclear if this is getting through some escape code or if this indicates a larger issue.

To recreate, go to a repository -> manage topics -> "test" -> Enter

Seems like a bug in Fomantic-UI based on that stack trace. Likely missing CSS.escape. Given that we are not updating Fomantic-UI anymore, we probably need a alternative JS solution for this tag entry, or move the remaining Fomantic JS into first-party vendor code and fix it there.

Actually / and \ is not supported:

---

Update: hmm, I see, the trailing \ causes the problem 😁 I guess it's not easy to fix and maybe no need to fix

I guess we could move the remaining fomantic source files to editable first-party files. Been meaning to to that for at least the CSS files, but also possible for the JS.
