Commands that trigger the issue

This may be a two-for-one issue. Let me know if I should split into two distinct issues.
This may be an MSYS2 issue, not a git-for-windows issue. Apologies in advance if that's the case.
This may be related to #6085

1. Font size changes aren't reflected in the options:

• open a bash window
• -> Options... -> Text
• observe the font size (default: Liberation Mono 8pt)
• without closing the options dialog, change the font size via ctrl-+ or ctrl--
• observe the font size is unchanged in the options dialog
• close and reopen the options dialog
• observe the font size is still unchanged, so it's not a refresh issue

2. Font size changes are lost when switching to a monitor with a different resolution

• open a bash window
• change the font size via ctrl-+ or ctrl--
• move the bash window to a monitor that has a different resolution; I have 2 external FHD 1920x1080 monitors and a builtin 4K 3840x2160
• observe that the font size has reverted to default
  This does not occur when moving between the two FHD monitors, only when moving between FHD and 4K monitors.

3. Bonus: The window seems to shrink some when the font size change is reverted.
   I haven't noticed this before so I'm pretty sure it's related to the font size reversion. I'm not digging into this one though due to time constraints.

Expected behaviour

I expected:

1. The font size change to be reflected in the options
2. The font size change to persist

Actual behaviour

See above

Apologies! Somewhere along the way I've lost the automatic "check for updates" functionality. I didn't know there was a newer version out with the scaling improvements.

I've since installed 2.55.0

$ git --version
git version 2.55.0.windows.2

and the altered font size works properly.

The options still doesn't update, but that may be by design?
Although if so, it precludes what I would expect to be a common use case: user sets the font size small, tweaks the size with ctrl-+ and ctrl-- until it's good for them, and then checks what the current setting is via the options. Then sets that as the default size.

Feel free to close this if the options part isn't a bug; the lost font size part is fixed in 2.55.0.
