bar: tooltip not follow when xAxis is crosshair and mouse move on empty part of chart

[zhangciwu]

Expected behaviour

when xAxis is crosshair, chart tooltip should be follow mouse when moving around empty part

Actual behaviour

when mouse moving on empty part

Wrong: tooltip is frozen, until hover on some bar
(at 5.0.9)

Right: tooltip follows mouse, showing at right bar
(at 5.0.7)

Live demo with steps to reproduce

Wrong (5.0.9): https://jsfiddle.net/ussn7b0j/1/

Seems all

P.S.

Internal Note: Was done deliberately in 13cfbe1 due to #6586.
Considering that bar is a series type with directTouch: true, this is actually intended behaviour.
Must be able to differentiate between these two behaviours in a logical way.

[zhangciwu]

1. wrong context for click callback (#6586)
2. hover blank area, expect to see tooltip for corresponding column, but not (this issue)
   In theory, these two issues seem to be irrelevant, so I think they should be all solved.
   Maybe some share code has bind them together, I'll spend some spare time to see if I can help this.
