[Selection] multi-user commands execute themself on the active sheet, even if the command was to be executed on another sheet

[VincentSchippefilt]

Steps to reproduce:

Open 2 browsers on the same sheet:
Alice on Sheet 1
Bob on sheet 2

Alice moves selection to the column Z (Sheet1, Z1)
Bob deletes columns from A to H (Sheet 2, A-H)

--> Alice's active cell on sheet 1 has been moved by the column delete of sheet 2, which is an error

Should be: If an action occurs on any sheet than the active sheet, the selection should not be impacted.

Side note: this creates a bunch of crashes because inserting columns can move the selection outside the active sheet size easilly
