WebUI.selectAllOption slow execution


When WebUI.selectAllOption is called on a select tag that has enabled multiple item selection, the selection is really slow and the items are selected one by one. There is the gif demonstrating the problem at the bottom of this post. This is painfully long when there is a list of 50+ items.

I was using Firefox in this example. I have also tried Chrome and same problem. I have been advised to post this as a bug.

Best regards
