(Bug?) a dash (-) in the search input filters out window titles containing a dash

[birgersp]

To reproduce:

• Create a folder named "my-folder" (note the dash in the name)
• Open the folder in an app (like files)
• Open Switcher and write "my-"
• Notice how the "my-folder" app is now missing from the list of filtered entries
• Effectively, the dash symbol in the search input doesn't match the dash symbol in the window title

See screenshots

Here you can see the "my-folder" window is in the list of searches:

Here I write "my-" but the dash filtered out the "my-folder" window:
