Summary

Occasionally, plots may be stuck in a state that represents a zoomed out level than the current zoom level for telemetry binning. This occurs after zooming in from large time ranges over several subsequent zoom ins. Once a plot has entered this zoomed-out-binning, it may not be removed from this state. Resizing the window or opening a large view of the plot does not fix it. Opening the plot in a new tab does fix it after synchronizing the time conductor, but is obviously not ideal behavior. The end result is that instead of the natural flow of telemetry, vertical lines representing the bins of the zoomed out plot are plotted instead of the better telemetry.

Expected vs Current Behavior

Zooming in and out should display the telemetry in the best way possible.

Steps to Reproduce

1. Load a plot somewhat zoomed out to force it to use minmax.
2. Zoom into an area of the plot. Note: The bug may appear at this point, but it's inconsistent.
