Treemap chart drillup button disappear after update the chart

[udeeshaIS]

Expected behaviour

If a treemap chart has updated in the drilled down state, drill up button should remain the same.

Actual behaviour

I was trying to update a property in a treemap chart on a button click. If the chart is in drilled down status the drill up button will disappear from the chart.

Hi @euiRulz

Thank you for reporting about the problem.

Workaround:
Preserve the button before update and reapply on the series after the update. Demo: https://jsfiddle.net/BlackLabel/tg7uzh8r/

Internal note:
Series update is not flexible enough to easily add new members to be preserved, so this could be resolved first. If we had not only afterUpdate, but also beforeUpdate then this could be resolved without changes in general Series. Third option is to provide update function for the series type, so this will be a wrapper without the usage of the H.wrap.
