While looking at history - maintain zoom level

[mjalindahl]

My dogs alerted me to something going on just now, and I went outside to join them and see what all the ruckus was about. When I went outside to see, I could see the reflection of eyes past my fence/gate. I knew it was a coyote. I didn't get alerted (fair enough, it's night time, and he was rather far away, that's not Frigate's fault).

So, I came back inside and immediately went to my cameras. I went to the camera's history, zoomed in on the spot by my mailbox that I saw the eyes, and then dragged the history bar. It zoomed back out. In all fairness, when you release the mouse button, it does go back to your zoomed in spot, so that's nice. It would be nice if the dragging of the history bar kept the same zoom so you can look at the spot you're already zoomed into. ¯_(ツ)_/¯
