Today my team met a weird bug on Safari browsers (on all Apple devices), that input losts its focus after you type first character.
First, we thought it's javascript bug so we wasted a lot of time for debugging the behaviour of input. But nothing works !
So we continued searching on Google, then we found this wonderful answer
The root issues caused by one CSS overrided -webkit-user-select to none, so we have to prevent it by add this line to end of CSS file
input, input:before, input:after {
-webkit-user-select: initial !important;
-khtml-user-select: initial !important;
-moz-user-select: initial !important;
-ms-user-select: initial !important;
user-select: initial !important;
} Hope it helpful for you next time ! :D
