[FIX] web_editor: prevent colorpicker close on click

Since Bootstrap was updagraded to 5.1.3, `ev.clickEvent` is no longer a
`JQuery.Event`. Therefore, the `originalEvent` property does not exist
anymore, and `__isColorpickerClick` can be accessed directly from
`ev.ClickEvent`.

By checking for the non-existent `originalEvent` property, the mechanism
that enables the colorpicker to remain open when clicked was being hindered.
Note that this handler's `ev` remains a `JQuery.Event`, and if a handler
returns `false`, it will prevent the default action and stop the event
propagating.
