Tab complete is problematic

[tormachris]

Tab complete is spotty. At times, when typing out a username (not sure if this happens with emotes), tab complete just refuses to work until I start over.

Tab complete also doesn't work if I type something, erase part of it and try to tab-complete. (For example pepoo backspace tab and nothing happens)

Something that has been bugging me a lot is that if you tab "too fast", no additional completions will be shown other then the first you tab to, e.g.
Comfy<tab> will complete ComfyApe but tabbing again will do nothing. If you type Comfy and wait 0.5-1s and tab multiple times, it will work.
To reproduce type comfy and <tab> very quickly twice (or more). It might have to do with the "auto-complete helper" loading in the background (I have it disabled though).

Tab-complete of usernames also breaks randomly "over time". A reconnect/reload fixes it. Root cause unknown.

Right is the long-running session that for an unknown reason removed the user, left is a new window https://i.imgur.com/q2pD83w.png
So seems like the name-tabbing bug is connect to user-state not updating correctly in some cases.

different bug: example string: " abc", with curser pos: " abc" (note the space in front of abc)
typing shy from that position results in "sh YEE", expected result: "shyLurk abc".

Reproducible if "YEE" in chat/autocomplete history; otherwise expected result.
