Color scheme preview via command palette and settings reload resets zoom level

[fran-f]

Windows Terminal version (or Windows build number)

Terminal 1.9.1942.0, Windows 10.0.19043.1165

Other Software

No response

Steps to reproduce

• Open Terminal
• Increase the font size with Ctrl-+
• Open the command palette with Ctrl-Shift-P
• Find "Select color scheme" and hit Enter to show the scheme list

As soon as the first color scheme is previewed, the zoom level is reset.

Expected Behavior

I would expect the zoom level to be indipendent from color schemes. Previewing or applying a new scheme should not reduce or increase the font size.

Actual Behavior

The color scheme preview affects the zoom level. Backing out of the menu will not revert this change.

You know, I could have sworn we had an issue tracking this! Right now, anything that causes a settings reload (or: "for new settings to be pushed into a terminal pane") destroys fragile things like font size and application-originated color scheme changes and the like. I searched the backlog high and low, however, and couldn't find one.

Congrats! This is now the tracking issue for that.

@zadjii-msft might be able to find it, too, but for now I'm just going to pull the triage tag off.

I did look for one as well, and I could not find any. The closest was #2874.

I don't think I ever filed anything like that. Turns out I'm probably gonna blow this all up anyways while working through an element of #5000, so I'm just gonna throw this on me for 1.12.
