User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36

Steps to reproduce:

Open multiple tabs, hold shift, click and hold on an inactive tab, move the cursor a bit (as you might when working quickly), release the mouse button.


Actual results:

Only the tab under the cursor is being dragged.


Expected results:

Tab multiselect should be triggered on mouse-down, not mouse-up, i.e. the tabs from the active tab to the tab under the cursor should be selected and all of them should be being dragged. This would mirror Chrome's behavior.
I suppose this should be added as a dependency to https://bugzilla.mozilla.org/show_bug.cgi?id=1458007
