Any review when editing comments

What steps will reproduce the problem?

  1. Start typing a comment on iOS with markdown disabled
  2. Tap and hold for about 3 seconds then let go

Note: the same issue happens on my iPad when the OS pops up the autocomplete hint bubbles above text when i misspell a word when markdown is disabled

expected results are that the context menu with things like copy, paste, and select are shown right away. actual results are that it freezes for up to 10 seconds

What operating system are you using? What browser?

iPad running the latest version of iOS. Browser is Safari
