Thunderbird 2.x doesn't exhibit this issue.
Firfox started to have this issue with 2.x release. Previous releases not affected. Firefox newest version affected as well.
Windows version irrelevant. Same problem when running Firefox on Linux platform.

This is a very old regression (or change, since it is not clear if it was done intentionally).

I tested on Windows XP with FF latest release 46.0 and latest Nightly 49.0 and I can't reproduce the issue.
Please retest this on the latest Firefox version and see if you can reproduce the problem.
