Clicking a select in a draggable item still drags the item on Firefox

Hello here's a bug report with <select/> elements in draggable items, only observed on Firefox. Thanks for this lib!

Repro steps

Here's a codesandbox showing the bug.

1. On Firefox, have a container where one or more items have a <select/>
2. Click a <select/> to open its options
3. Don't select any option and move the mouse up/down

Expected result

The item containing the <select /> shouldn't be considered to be dragged and shouldn't move.

Actual result

The item moves around with the mouse.
