Shift + Double Clicking on empty space creates a selection

[MightyBOBcnc]

Title. If you have a selection, such as an edge, and it is the active edge, and then you Shift + Double Click on empty space in the viewport it creates a selection.

The reason for this appears to be that in Blender's default keybinds only a regular Click is set up to do "deselect on nothing." Shift + Click (as well as all other variants of [Modifier] + Click) does not have "deselect on nothing" enabled.

• I can't think of a passive way to fix this without doing our own raycasting (and I don't want to deal with the performance impact of raycasting).
• It might be possible to forcefully override the existing keymap entries for the view3d.select operator to enable "deselect on nothing" for all of the [Modifier] + Click actions in the viewport (but I don't want to force an invisible and possibly unwanted change on users; maybe it could be a toggle in the addon preferences?).
• For now the only real solution seems to be to live with the "bug" and just tell users to change the keymap themselves if it is bothering them too much.
