Treemap first renders incorrectly when yAxis is added via addAxis

[anajavi]

Expected behaviour

The treemap should render correctly on first render. When yAxis is added in chart config this happens.

Actual behaviour

The first render doesn't set colors and legend. After resizing window, the colors and legend display correctly.

Live demo with steps to reproduce

https://jsfiddle.net/brdjj8y7/3/

First the colors are all black, and legend does not show numbers. After resizing window the chart renders with blue colors and legend with numbers

Product version

Highcharts 6.1.0

Affected browser(s)

Tested: Chrome latest, Safari latest

Hi @anajavi

Thank you for reporting about the problem.

As a workaround you could set min and max for the color axis - https://jsfiddle.net/BlackLabel/brdjj8y7/4/
