test case

AccessibilityTable::isDataTable() needs an update that excludes elements from most of the heuristic considerations if the element is not a native <table> element.

In other words, no matter its style properties, an element should never be exposed as AXTable unless the element is <table>, or explicitly uses "table", "grid", or "treegrid" as the value of the role attribute. The additional heuristics like border detection should only be applied to <table> elements that have no explicit role.

Test case from Marco Ranon:
