Wrong value appears whennumerous clicks are performed on "Plus" button

[NorrNext]

I noticed one unpleasant issue on the checkout.
Joomla 5, VM 4, customized Cassiopeia template.
I added an item and proceed to the checkout. then I decided quickly to increase amount of an item from 1 to 10 and make quick multiple clicks on «Plus» icon.  And... I see there is a bug. The number increases: 1,2,3,4 and then the number returns back to 3 after a quick click. then I continue to click on plus and it's again 4,5,6 and etc.
So, when I perform quick clicking on «plus» icon, sometimes the value decreases instead of increasing.



VirtueMart 4.4.4 11101, Joomla 5.2.3

It takes time for AJAX request to complete. One option is to disable the button until it completes. Another is to add a delay between the click and the request.
