thunderbird zoom in not sticking

[Mitch Claborn]

The View, Zoom In setting does not stick in all cases.

Example:
- looking at a long list of emails in a folder
- press Ctrl + + twice to zoom in
- copy some text from one of the emails, paste into the filter box
- press Ctrl + A to select all the filtered messages
- press shift + Del to delete those messages
- clear the filter box so that all emails show again
- click on on of the remaining messages to see it
- message window has reverted to the default zoom level

I have noticed that the zoom resets to default in other situations as well, but this one is easy to reproduce.
