New "\" shortcut for "select parent" types the backslash into design-palette fields

I love the new backslash shortcut for “select parent.” However, unlike Shift+Enter, it doesn’t work when any field in the design palette has focus. Instead, it types the backslash into the field.

I can’t conceive of a reason to need a backslash in a numeric design-palette field: e.g., it’s not a mathematical operator. So can Figma disallow such an entry and instead select the parent?
