Current behavior

Having an untrimmed text value will lead to bad behavior when changing the language twice
'untrimmed':
<button translate>text </button>

Expected behavior

• translation will not work once
• or translation will work as often as you change language

How do you think that we should fix this?

As i took a look at the code it seems like a caching / comparing problem.
So fix the code.

maybe it depends on #808 but hopefully more reproducable
