In RTL, blocks don't return to their position after dragging outside the area #2094
Description
Expected Behavior
When blocks are dragged outside the area, they should reappear in their original position.
Actual Behavior
In LTR this works as expected. In RTL, the blocks appear in another position.
Steps to Reproduce
Open vertical_playground.html. Change direction to RTL. Add a block to the area. Drag it outside the area, to the pane on the left. It appears in another position.
(I noticed this in scratch, when copying a block into another sprite by dragging it. The block is moved to another position.)
