Hello,

I am encountering an unexpected and unpleasant behavior of tag "invisible".

As a minimal example consider code:

lemma A ==> A proof-   assume A   then show A    by simp qed
I want to see:

lemma A ==> A proof-   assume A   then show A qed
However, writing

lemma A ==> A proof-   assume A   then show A    by simp ✐‹tag invisible› qed
one gets in the output document the following:

lemma A ==> A proof-   assume A   then show Aqed
Is this intended? Is there a way to put the "qed" on the new line?

Thanks.

Stepan
