Only if you accept that it overflows above the install button, I'm not sure that's better.
You're right, it does overflow with some of the translations.
This seems like the safest way to add it:

I checked the longest `Install theme` translation, which is Lithuanian, and it doesn't overflow:

Alternatively, the `Color` combo box could be moved to the first row like so:

Which of these would be most preferable? I'm leaning towards the second one.
