Dirty exit dialog choice is ignored

[per1234]

Describe the bug
When closing a sketch with unsaved changes, the user is prompted whether they want to exit without saving "Are you sure you want to close the sketch?":

If they click the "No" button, the exit occurs anyway and the unsaved changes are lost.

To Reproduce
Steps to reproduce the behavior:

1. File > Preferences
2. Uncheck the box next to "Auto save".
3. Click the "OK" button.
4. Make changes to a sketch without saving.
5. Close the sketch (by doing any of File > Close, File > Quit, or closing the window). The "Are you sure you want to close the sketch?" should be shown.
6. Click the "No" button. The sketch will close anyway and the unsaved changes will be lost.

Expected behavior
When the user clicks "No" on the "Are you sure you want to close the sketch?" dialog, the sketch should not be closed.

It works on macOS, but I could reproduce it on Windows. I need to verify it on Linux too.

I have fixed and verified it on Windows. We will make this available to the public soon.
