[FIX] web_editor: enter should be caught by image editor

Current behaviour before commit:

When cropping an image, pressing ENTER creates new paragraph behind the
widget, due to this, changes are not getting applied on image and it disappears.

Desired behaviour after commit:

Now hitting ENTER works same as apply button, Changes are getting applied
when pressing ENTER.
