Description

The new web UI looks nice, but I almost didn't find a way back after zooming in:

If I click twice into the job graph of a running job, the graph zooms in. After clicking multiple times, it got too large and I wanted to zoom out:

• the zoom slider was not clearly visible (blue on a blue operator behind it)
• the mouse wheel did not zoom (neither in nor out)

Can we make this a bit more visible / accessible?
