don't force absolute time when zooming timeseries view

Describe the annoyance

Sometimes I want to adjust the X-axis of a TimeSeries plot to zoom out and see a larger range. When the view range is set to current time with offset, any scrolling will also set the axis to absolute time, which is not what I want, since that then stops following new data.

To Reproduce

1. set a TimeSeries to current time with offset
2. zoom using Shift + Scroll (so only scaling X-axis)
3. view range gets changed to absolute time

Expected behavior

I think it would be better if the viewer were to detect this, and scale the offset amount, instead of resetting back to absolute time.
