FWIW, such modus operandi always annoys me.  Why should I be under
pressure to do whatever is needed to prevent the setting from being
reset?

I don't really understand what's the problem with "mode-ish
operation", feel free to elaborate.

If there's demand for resetting the size, I guess we could have it as
optional behavior.

The user can always scale the size back when she wants, right?  Or am
I missing something?
