Selection incorrectly set when right-clicking the 1st task at the top of the task browser

Since the GTK4 port:

If you have 3 tasks shown in the tasks browser, right-clicking the 2nd or 3rd task will correctly select them before opening the menu, but right-clicking the 1st task at the top opens the contextual menu without selecting the task.

It turns out that this is not necessarily dependent on the amount of tasks, but always about the 1st task in the list, as this video shows:
