Thank you for the report, Marcelo.

As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved.

Comment 2 Marcelo Jimenez 2020-12-03 04:23:49 UTC 
Hi Justin,

It has been quite a while, I don't think that this is still relevant.

It is "resolved" "hopefully". :)

Regards,
Marcelo.
