Bug in LXTerminal restore down window behaviour on PiOS Bullseye with openbox window manager

[ghost]

I've come across an odd bug in the behaviour of LXTerminal on the default Raspberry Pi OS Bullseye 32-bit install. This is on a fully up-to-date system.

The issue is as follows:

1. Click 'Terminal' from the menu, or the black CLI quicklaunch icon: LXTerminal starts up as a normal window, with default size 80 x 24 lines.
2. Click maximise button on Terminal window - window correctly maximises.
3. Click restore down button on Terminal window - window correctly restores down to a normal window.
4. SOMETIMES the Terminal window, after correctly restoring down, immediately expands to almost full screen just smaller than the size it was when it was maximised. There doesn't seem to be any obvious pattern to it - it seems to be random and happens very roughly 50% of the time.

This only happens with the openbox window manager - with mutter, which is the default window manager on Pi 4s with >= 2GB RAM, the restore down behaviour is correct 100% of the time.

I don't know what is causing this, but since the problem manifests on LXterminal, I'm filing against this repo. Feel free to close as won't fix.

LXTerminal does some very odd things graphically from time to time - I think due to having the ability to run in a partially transparent mode - and this sounds like one of them. I'll stick it on the list to look at when I get some time.
