Mouse events show up as characters in the terminal instead of being handled

What Operating System(s) are you seeing this problem on?

macOS

Which Wayland compositor or X11 Window manager(s) are you using?

No response

WezTerm version

wezterm 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

I have been noticing this bug for a while. I have long running ssh sessions (using regular ssh, not the one integrated in wezterm) when I'm at work. Then, I close my laptop, and head to the train station. When I board the train, I open the laptop and it tethers with my phone. Naturally, this causes the ssh connection to break, so I redo ssh to the same host. This is when the issue start.

If I try to scroll up/down via the trackpad on Mac (two finger scroll) instead of scrolling, the current line fills with symbols like:

`B`B`BBaBaBa

The worst is, I can't even select the text with the mouse (as I'm used to), as that just emits:

 U#U

This is how it looks like. I don't even need to be ssh'd or ssh again, just wake my computer from sleep and start moving mouse to scroll in a terminated ssh session, where during the sleep I changed the network.

Mouse events remain on until turned off by the application. You can use the command palette to reset the terminal emulator state to recover from this. It is not a bug in wezterm; the same would apply to any terminal.

@wez can you elaborate on command palette to reset the terminal emulator ?

I tried Esc c from https://wezfurlong.org/wezterm/config/lua/keyassignment/ResetTerminal.html but no luck

I also have issue with mouse events generating characters sometimes, maybe after mac goes to sleep. And yes, I had same issues sometimes in iTerm. It disappears on new tab.

Running reset command helps
