Why do search bars close before keyboard can come up: Android Opera?

In top bar that "search" option including logged in or not will come up but when I go to click a box to search on any Android using Opera, I have tried Android 5.1.1 Lollipop and Android 13, like current version, it disappears before like my keyboard can come up, then like my keyboard closes because there is nothing to write to. Any box in search does this. I can do advanced search and that works fine but other than that, no search possible. I can't get a screenshot, it would have to be a screen video. In Android 13 Chrome works like Opera. X E.
