Wezterm does not show User/Host for ZSH when using SSH
What Operating System(s) are you seeing this problem on?
Linux X11, Linux Wayland, macOS, FreeBSD X11, FreeBSD Wayland
Which Wayland compositor or X11 Window manager(s) are you using?
Gnome/mutter/x11
WezTerm version
20240203-110809-5046fc22
Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?
No, and I'll explain why below
Describe the bug
Tabs running bash are able to show their username and hostname in the tab and windowname.
This does not happen when running zsh
This is true when running bash/zsh locally as well as on other hosts using ssh.
I did not try the latest nightly because no functionality like this is mentioned in the changelogs.
To Reproduce
Open wezterm and open bash if it is not your default. Note the username and hostname included in th tab title and the window title
Now open zsh - note how username and hostname are now absent.
You can repeat this while ssh'd into various clients and the hostname and username are correct.
I have tried ssh into freebsd, ubuntu latest(24.04), arch latest, and macos latest (sonoma) and the behavior is the same with each.

Expected Behavior
Tabs using zsh should show the username and hostname in the tab title, same as on bash.

Anything else?
Id ideally love to have these as variables exposed inside of the wezterm configuration so that we can add or subtract the hostname from the tab name as part of wezterm configuration instead of having them be tied to zsh/bash
The only other callout I have is that this functionality works correctly on other terminal emulators such as gnome terminal, gnome console, and ITerm2. All three of those have the same tab naming on bash and zsh so im not sure what makes it different for wezterm.
Most likely cause is that one of those environments is not consistently using OSC 0, 1 or 2 (https://wezfurlong.org/wezterm/escape-sequences.html#operating-system-command-sequences) to set the title.
The default behavior in wezterm is to try to determine the current process by querying the local system. However, as soon as the title is changed for a pane, wezterm will no longer try to query the system and will instead trust that the title set by the escape sequence is correct and is maintained by the program you are running in the pane.
I would suggest debugging your shell startup to see what is happening. It can be helpful to set -x to see what they are up to.
Another factor to consider is that wezterm always starts your local shell as a login shell, which can also affect which of your shell startup files are processed.
