Vaadin Designer Edit mode doesn't work

[bbengamin]

Actual behavior
When I edit the design files using Edit mode changes don't reflect HTML structure or auto-generated java files.

Expected behavior
When I edit design file using Edit mode changes are saved in HTML and auto-generated java files

I created a short video to show you the problem - https://www.loom.com/share/d65980a8155f497f833143554c73fb28.

@szolo could you please try to reproduce this issue on your side with Designer?

Hello @mshabarov, sure! Probably this particular MPR setup is an issue.
