SUMMARY 1. In Kate, save two different sessions, lets say Foo and Bar. 2. Close all Kate windows. 3. In the launcher / krunner, search Foo to open the first named Kate session. 4. With this session still open, do the same again for the second named session, Bar. Result: the existing window containing the first session is replaced with the second session. (If I wanted to do this I would do so through the window's menus.) Expected (and old behaviour): launches a new Kate window with the second session. SOFTWARE/OS VERSIONS Fedora 37 beta, Wayland.
Thank you for the bug report! Please note that Plasma 5.25.2 is not supported for much longer by KDE; supported versions are 5.24, and 5.26 or newer. If at all possible please upgrade to a supported version and verify that the bug is still happening there. If you're unsure how to do this, contact your distributor about it.
Cannot reproduce with git master everything, also on Fedora 36. When I do this, the second session opens in a new window. It must have been fixed in later versions of KRunner and/or Kate.
This was fixed by https://invent.kde.org/utilities/kate/-/commit/ec25d9f636b993bc2da91c3d20dfe632c72a21a7 already
