[1.1.61] 'E' to confirm stack size override after double-clicking

[SupplyDepoo]

'E' does not save the changed stack size override if you double-clicked the edit box.

Steps to reproduce:

1. Open inserter GUI
2. Check 'Override stack size'
3. Double-click on edit box (note: initial value is 2 after teching to inserter capacity bonus 2)
4. Type '1'
5. Press 'E' to confirm.
