Display relation field select list if focus is activated
Fixup click handling

(fix: e46ade7a)

(fix erp5.git/eb5f1fb1)

As it is a common pattern to set validators on hidden fields
to display custom errors to users.

By using `os.path.normpath` we also support paths with a trailing slash.

Also, change the JSON format and update tests according to these changes

The script though that user was scrolling the test output while in reality we just
add a tiny difference of 0.5 pixel.

This first reverts the following 2 commits:
  566c0c5f
  3a08c758

to at least fix the issue that the context method takes 2 arguments that aren't
available from FormBoxEditor.edit() without slowing things even more.

About deferred style, widget editor objects can be ignored for the moment. If
we ever need to restore fully functional objects, the regression in commit
  a5a2f1cd
could be solved with the following patch:
