The issue seems to be reproducible with any browseable message. Here is an example with the format reporting command.

Steps to reproduce:

• Go somewhere where the formatting command has something to report, e.g. in Windows commands console (cmd).
• Press twice NVDA+f to display formatting information in a browseable message
• Alt+Tab to the console
• Reload the plugins with NVDA+control+f3
• Alt+Tab somewhere else or move the focus elsewhere in some way.

Actual behavior:

The new focus is not reported.

Expected behavior:

The new focus should be reported.
