Safari and dictation, it’s getting worse

Dictation was one of the best things about iOS previously, and it’s always been fairly stable for me anyway but recently in Safari using the latest version of iOS 14.4, I’ve noticed a very annoying bug.
when I use dictation to enter text into Google search bar, and then try to navigate back through that text to edit it, voice-over won’t read out what I’m swiping back through although I can still hear the keyboard clicks, this can last for 10 seconds or more and sometimes I will have to close the search box and reopen it so the voice-over will work again.
and happens about 80 or 90% of the time now, and only in Safari for some reason.
