Description
For https://bugzilla.mozilla.org/show_bug.cgi?id=1650336, we want to differentiate markers originating from different WebConsole UIs by adding an ID unique to a given WebConsole.
This allows us to see markers for each WebConsole UI on separate lines in the MarkerChart tab.
But it makes for really long marker labels, eg `WebconsoleAddMessages (server1.conn0.parentProcessTarget2)`.
In the MarkerChart sidebar, they are rendered with an ellipsis:

It would be great if hovering on the marker's label would show a tooltip revealing the complete name.
