How to reproduce the issue?

• Set your language to en-*, and use a keyboard layout with a ⌫ Backspace button.
• Create an area tagged with building=yes + shop=yes
• Select the area that you just created
• 💥 Press ⌫ Backspace, and note how nothing happens
• Now right click the area, and choose "Downgrade". Note how the downgrade operation works via the menu (even though it didn't work when we pressed ⌫ Backspace)

Screenshot(s) or anything else?

(image to avoid confusion. I don't know if this bug also affects apple keyboards that label the button differently)
