[FIX] web_editor: fix MouseEvent in checkbox tests

When the test suit is run in Chrome with zoom level different than
100%, the tests than toggle list checkboxes fail.

This is due to the lack of the "view" option in the simulated MouseClick
event. When not present, it defaults to null and the mouse coordinates
get messed up when the zoom level is not 100%.

This affects only the tests, not the actual application.
