Table selected cell

[Marc-Andre-Rivet]

When a cell with default background color is active, a highlight color is applied.

When a cell with a style_** background color is active, the highlight color is not visible.

This also applies to selected cells.

The active/selected styling is currently done through css here and here -- this styling should be done through the styling pipeline / derivations. For example, the data cells here

The change should be similar to what has already been done for the active cell's border here
