Tvheadend

When I start clicking on a field and typing, it seems to try and auto-complete the field which wipes out whatever I was typing. See example here. I'm trying to type 'sky' but you'll see that every time I type a letter it starts searching and I can't continue.

Scrolling through the options works fine, it's just a lot slower.

Not sure if this is a bug but it drives me mad

I'm using OSX and I've tried in Chrome and Firefox. It's TVH version 4.3, running the linuxserver/tvheadend image in a docker container.

Would appreciate any advice. Thanks!
