3. Open the project in pycharm

OBSERVED RESULT
Window title in the icons-only task manager calls the window "craft"

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: Kubuntu 23.10
(available in About System)
KDE Plasma Version: 5.27.8
KDE Frameworks Version: 5.27.8

ADDITIONAL INFORMATION
Using the "Detect Window Properties" item in System Settings's window rules segment shows the correct window title.

This occurs both on Wayland on my laptop (running Kubuntu Mantic) and on xorg on my desktop (running KDE Neon)

Heh, we use the hyphen to cut of the app name, but it looks like we're inappropriately looking for the first one rather than the last one.

We do look for the last one, it's just that Pychar uses – instead of — or - (they're all different). I added that dash to the list and, just for sure, also checked for whitespace before it.

In Task Manager tooltips, only match dash if it follows a space

Since some applications might have a project with a dash in the name,
such as "python-Project", we only match "-" in the tooltip of Task Manager
(to extract the project name) if there's a space before it. We also start
tracking for –, which is a different type of dash compared to -.
