Explanation

• What is the behavior you expect?
  I expect the selection pane in the brush charts keeps always stable.
• What is happening instead?
  When I start a new selection from right to left and then select it and slide to left the selection pane goes out of the brush chart and starts to have erratic behavior.
• What error message are you getting?
  None.

I have the same issue, furthermore I have the issue that I can start the selection of the brush chart, outside of the chart. e.g. by clicking on the left yAxis. See the gif below for details:
