Windows 10
Thunderbird version 102.5.0

There are many frustrated people commenting in Support Forum. It always seems worse for those who have never used or seen the 'threaded' view. So clicking on the top level collapsed folder and it rendering dozens of emails to open in dozens of tabs made people concerned about weird bugs etc etc.
People need to be able to set 'unthreaded' on an entire account.

It only works if you only select one folder as follows

- Select Inbox
- Set 'View' > 'Sort by' > as 'Unthreaded'
- Right click on column headers and select 'Apply current view to..' > 'Folder and it's children' > select 'mail account name' and then 'choose a specific top level folder' - not a mail account name folder - which you already know has a 'threaded' setting.

However, this is not a practical solution when you have to do this to all folders in all accounts - one top level folder at a time.

You need to have the following - which is available to select - to work.
- Select Inbox
- Set 'View' > 'Sort by' > as 'Unthreaded'
- Right click on column headers and select 'Apply current view to..' > 'Folder and it's children' > select 'mail account name' and then 'mail account name'
- Repeat the line immediately above to select other mail accounts.

It does then have a pop up saying that it gets applied to all folders in the mail account.
This should force an unthreaded sort into all folders in that selected mail account.
But it does not. 
Any folders with threaded already selected either manually or by default remain threaded.

I'm creating this as a separate bug as requested by Magnus.
Relates to previous bug fix: 574986
