Ipad Brave refresh page button changes

I use Brave on my ipad Air 3rd generation,version 16.7.2. In what appears to be entirely random behaviour the page reload/refresh button works in 2 different ways. Sometimes it refreshes the page immediately (as I think it should and how all other browsers work) and the other way it shows the URL highlighted and needs me to press the enter key to reload the page. I’ve never seen another browser do the latter, it appears to be random.
