Steps to reproduce:
# Create a new Unity project
# Go to menu "Unity" -> "Shortcuts"
# Verify, that the "Shortcuts" window opens
# In the profile drop-down menu select "Create new profile"
# Observe the "Create profile" window
# Try to resize it. Verify, that it doesn't work.
# In the profile drop-down menu select "Rename profile"
# Observe the "Rename profile" window
# Try to resize it. Verify, that it doesn't work.
# In the profile drop-down menu select "Delete profile"
# Observe the "Delete profile" window
# Try to resize it. Verify, that it works.

Expected result: All three modals should have consistent UI and behavior. The user should not be able to resize the "Delete profile" window.

Actual result: The "Delete profile" window has a different behavior compared with the "Create new profile" or "Rename profile". It can be resized. And during it modal has empty spaces. Added screenshot in the "Attachments" section.
