[4.9.29] - 2020-07-09

Export: data exported as HTML will now have <thead> and <tbody> tags.
XYChart.getClosest() method is now public.
Accessibility: Now pressing ENTER while there's a MapChart element focused (using TAB key) will invoke its hit event, if set.

JSON: heat rules referring to series' bullets were not working, e.g. target: "bullet[0].circle".
IE: More fixes to polyfill overriding.
ColorSet method next() would fail if currentStep was bigger than minColors, affecting SliceGrouper plugin setups with a lot of slices in particular.
On MapChart settings minZoomLevel and maxZoomLevel were being ignored when pinch-zooming.
Syncing of axes improved, especially when series of one axis were hidden/shown.
If a MapSeries had its geodata loaded via geodataSource, the map used to disappear after div size changed.
Legend had a maxWidth set to 200 and this could result labels to be truncated even if there was enough space for them to fit in.
Ticks/grid could disappear if ValueAxis had min/max set and data of a chart changed.
