In the PR #97692, writing empty str `''` to a model term field no longer removes
all translations. Instead, only the translation for the current language is set
to empty str `''`.
Before this fix, if a web user sets a translation to emtpy str, and reopens
the translation dialog, the translation will be reverted to the 'en_US' value
which is wrong.
