Dragging components does not work in Firefox

[igorvanoostveen]

Observed behavior

When using Firefox, a user tries to drag a component from the component library (on the left hand side of the window), but no component is dragged and a selection area appears in the component library.

Expected behavior

To be able to drag components from the components library like on other browsers (tested Chrome).

Details

Observed in Firefox 80.0.1, Firefox 81.0, Firefox Nightly 83.0a1 (2020-09-28).
