[LH3541] Bug? New document, change font, cursor disappears.

I create a new document. Empty.
Click in it. It’s currently “No Style.”
Change the font of “No Style.”
Typing cursor goes away.

If I type in the document (I can type in it, even without a typing cursor), the cursor comes back. If I click another style and then “No Style” the cursor comes back. But only clicking in the document does not produce the expected cursor.

Thanks. This has been filed.
