No one has replied. So really looking forward to your ideas and suggestions.
FYI, the buttons on the sliding panel that residual of them shows when the panel is in slide out mode, their parent DIV does have overflow: hidden
But still Apple iOS safari is showing these residuals of these buttons when Panel is on slide out mode which is parent Width = 0!
And what do you mean exactly by using position Absolute to get around the Apple Bug in regard to cursor in input Text? Of course I know Position on CSS, but not sure how this would get around this Apple bug! FYI, I actually had these input Text fields displayed via Position Absolute, and this cursor bug was even worse! So switched to non Position placement, and using more basic CSS placement. But still as you can see the problem persists.
