AST trows a warning for a button with theme with states

[KacperMadej]

Behaviour

If states are used in buttonTheme I get a warning in the console:
Highcharts warning: Invalid attribute 'states' in config

Live demo with steps to reproduce

https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/stock/rangeselector/styling/

or

https://api.highcharts.com/highcharts/chart.resetZoomButton.theme
Steps: zoom to show the button -> warning

Product version

v9.0.0+

Workaround

Ignore it - everything works fine anyway.

Internal notes

states end up in normalState (from the theme), but could be safely deleted before running AST.filterUserAttributes(normalState) because normalState is already a copy and states are provided to SVGRenderer.prototype.button as arguments and later used from them

@TorsteinHonsi @KacperMadej @DJTechnoo I'm seeing this warning in HC 10.0.0... seems to have re-appeared?

Steps to reproduce:

• Open the Theming the button demo linked from https://api.highcharts.com/highcharts/chart.resetZoomButton.theme
• zoom to show the button
• warning is shown in console

BTW is it possible to add a top padding for the button text (or a negative bottom padding)? I'm finding that the text is sitting a little high in the button:

Thanks! The fix for this issue only fixed range selector and map navigation buttons. So we should probably dig a bit deeper to try to cover all kinds of buttons.

Regarding offsetting the text, there is currently no API option for it, but CSS transform seems to work fine: https://jsfiddle.net/highcharts/eLkfz40w/
