Plotly.react during axis drag

[mitja-p]

I have a plot with live data and sometimes when dragging the x axis the plotted signal moves, but the axis doesn't move. I found issue #3305 and there the example https://codepen.io/swiperii/pen/wyPEBW?editors=0010 which reproduces my problem totally. Click Add data and then drag the x axis. Wait and you will see that the signal and axis jump back when new data arrives. If you move the signal more the signal moves as before, but the axis stays fixed.

As far as I am concerned during dragging / zooming the layout should stay the same and nothing should jump back to original plot.
Can anyone tell me what is happening here?

I was debugging the code and noticed that when it fails the axis object in gd._fulllayout and the axis object in dragbox are not the same. It then fails to update the axis due to:

dragbox.js, ticksAndAnnotations method:
var ax = getFromId(gd, axId);

this gets axis from gd not the axis used and calculated in dragbox and it then draws that axis which was not update instead of the updated one.

Workaround is to call gd._fullLayout._redrag() with a timeout of 0 seconds on startrelayouting event. This seems to fix things and from then on it works fine.
