Can't cancel drag from Finder using ”esc” if activating app switcher (cmd tab) and switching to another app

Originator:staraffinity

Status:Open Resolved:
Product:macOS + SDK Product Version:10.12.3
Classification:Usability issue Reproducible:Yes
 
Area:
Finder

Summary:
If one grabs an item from the Finder (while the Finder is the frontmost application) and while ”holding” the item activates the app switcher (cmd tab) and switches to another app (while still ”holding” the Finder item) it's not possible to cancel the drag in the other application.

Steps to Reproduce:
1. Have the Finder as the active app and at least one other app running.

2. Grab an item in the desktop (for example) and while ”holding” it (i.e. mouse/trackpad down) activate the app switcher (cmd tab) and switch to another app (for example Safari).

3. Now, try to cancel the drag using the ”esc” key.

Expected Results:
Nothing happens when pressing ”esc”, though it should lead to the drag being canceled out.

Actual Results:
Nothing happens, i.e. the item is still ”held”.

Version:
10.12.3 (16D32)

Notes:
It seems the ”esc” press still goes through to the application being in front, but I think macOS should first check if any item is currently ”being dragged” and cancel that out first.

Comments

Same behaviour also happens between other apps

If one item is grabbed while one application is in the front, and then (while holding the item) one switches to another app (using cmd tab) the item being held can't be canceled out.
