recently use the 2.2.1 version of element-ui a lot of button clicks, especially the tabs tab components will appear after clicking this border style, not immediately show this border style, is clicked indefinite time after some time will default to add this, test n times the real time is not fixed and not every time, it is very helpless to find a solution.
I would like to ask you if you have encountered the same problem and asked for a solution.
