plotBand of highcharts not accessibile

Hi,

I am trying to implement accessibility(keyboard navigation on hover state). When I hover the plot band I can see the tooltip values as given by moveover event. But when I tab into it I can see that the borders are highlighted but no data of hover state(ie. the tooltip) is shown. I have attached a fiddle for the same.

PS: I have even added zIndex to the plotbands and fill-opacity:0 for the series. Any help?

I prepared a simplified demo, please let's work on this If there will be a need, your example it's a bit complicated for tests.
