@andreicristianpetcu Does turning off 'Wait Until First Paint To Show Page Content' secret setting fix the issue?

[hwinnemoe]

I can reproduce on Nightly 200820 06:08 (Build #2015759025) using the following STR:

1. Have the _Wait Until First Paint To Show Page Content_ secret setting activated
2. Open a tab in non-PBM, e.g. https://www.mozilla.org/en-GB/
3. Long-press a link and tap _Open link in private tab_
4. Wait for the snackbar to disappear
5. Switch to PBM and open the new tab

Actual behaviour

Closing this as duplicate.
@andreicristianpetcu If you do not have 'Wait Until First Paint To Show Page Content' option switched on, please reopen this. In that case, a stack trace would be useful. Thank you!
