Option to remove border between the stacked graph about highcharts

[bm64]

Hello @mayur249 and thanks for sharing the idea.

This topic was brought up on stack overflow some time ago too: https://stackoverflow.com/questions/64334052/need-a-single-border-for-stacked-bar-graph-in-highcharts
Suggested workaround was to use a dummy series to create a border:

Hello @bm64, thank you so much for giving your time for sharing this solution.
One issue I noticed with this solution is that if we want to hover over a particular stack in a bar, we can't do it because it is considering that I am hovering over an entire bar

But for this zIndex was the solution so I applied that and got the solution.

Added the solution in this jsfiddle: https://jsfiddle.net/mayur249/21bp6tjy/

But @bm64, after applying the above solution, there is one more problem that I am facing.
This problem is related to another feature request which I have raised: https://github.com/highcharts/highcharts/issues/20781

The thing is if the stack's value which is at top is zero, I want to change the border radius of the below stacked column dynamically. But currently I am not getting any option to do that. So because of that I am facing this issue here:

@mayur249 An alternative to setting the zIndex is to apply pointer-events: none. That way the border is not clipped: https://jsfiddle.net/highcharts/ycpa8svt/
