Click has 300ms delay in iOS 16+

[DustinBrett]

Single clicking an entry looks like clicking, bluring, clicking.

[DustinBrett]

• Also makes double clicking harder
• Involves the isSafari touch additions possibly
• Safari triggers mouse down after touches
• Selecting an entry flashes unselected for a moment (iOS)

[DustinBrett]

• Nothing to do with isSafari
• Happens on iOS 18 with an iPhone 16 Pro Max in BrowserStack & with my test iPhone 13
• is focused on FileEntry click as doesn't focus
  • Giving it focus via as or tabindex didn't help the main issue
  1. focusEntry & blurEntry aren't relevant
  2. Hover is triggered before click
  3. Double clicking is very difficult because of this
     • Need to wait 100-200ms between clicks

[DustinBrett]

• onDoubleClick didn't work in Safari
• Even putting onClick on other elements or testing a click website, I found that in iOS on BrowserStack, you can barely ever trigger 2 onClick events within 400ms of each other
• isFileManagerFocus is true in iOS because the button click doesn't focus the button, but even if we fix this the original bug remains
• onMouseOver is also triggered in iOS as it emulates a hover effect

[DustinBrett]

• Only happens in Safari 16+
  • Issue isn't happening in iOS 14-15
• Touchend and all other action events have the same delay
• touch-action didn't help on element, body, html
• FastClick library doesn't help
• Visual flicker was caused by tap highlight and not related to the double click issue
  • Fix with -webkit-tap-highlight-color
