Issue in desktop safari 13.1.1

[gilbert]

An internal error was encountered in the Indexed Database server

Screenshot:

To reproduce, run the previous step once and this step twice from the quickstart page. The first time works, but the second time fails, and afterwards all other fs operations throw the same error.

You can also reproduce from scratch by starting with a fresh incognito window.

I found this bug in a search, but that seems to be iOS Safari. Anyone know of a workaround for this?
