Cannot update changed messages in the dictionary

[cbxp]

Describe the bug
Snowpack hot reload receives updated json translations and tries to pass them to addMessages() again.
However, _() still returns old texts after that.

To Reproduce
Just call addMessages() twice with different texts and see that second call has no effect.

Expected behavior
I expect the addMessages() to override the texts, so that _() would return new ones.

It seems that the dictionary is updated, but there is no way to clear the lookupCache, so _() returns old values
