When the chart is configured to use the selection zoom. One must press the Shift-Key and select an area inside the chart to zoom.
I the chart shows tooltips, in most cases the tooltip pops up under the cursor and it is not possible to select an area.
The tooltip shoud be disabled, when the shift-key (or the configured key) is pressed inside the chart area.
When using the "checkBy" attribute to configure the data field for the key definition, then the indeterminate state of parent nodes is broken.
To reproduce the issue have a look to this StackBlitz: https://stackblitz.com/edit/angular-okpokx
