Anybody experiencing issues with tabs on safari?

I'm using safari with voiceover on the latest version of IOS, and am coming across what seems to be a bug when looking at my tabs list. Sometimes a double tap will close a tab instead of selecting it, even when I've flicked up and down to make sure it's on activate instead of close. It doesn't seem to be consistant, sometimes it works perfectly but seems more often not.

Does this happen to anyone else? Is there something I'm not doing that I should be? It's slightly frustrating when it does happen!
