Expected behavior

Pressing shift + backspace (or delete) deletes cells. Holding shift while typing in a cell backspaces the edited text.

Actual behavior

Pressing shift cancels any edit action on a cell, both in the editor and when deleting a cell. This is frustrating as it’s common to hold shift while navigating a spreadsheet or selecting ranges. It prevents users from editing without remembering to “unshift”.
