UX issue: Grab scroll resets zoom

Thanks for the video but I don’t fully understand, can you describe a little more in details ?

hi so I zoom out using my G and H keys, then use middle mouse to grab move around but it resets the zoom to full

Also just noticed, the middle-mouse button grab-scroll doesn’t work with the playback tool

This occurs when width zoomed out greater than the width of the event itself, ie, zoomed out so that there is non-event null space, and then trying to grab scroll
