Add a focus feedback to invalid cells in Worksheet

[MariaJose]

Is your feature request related to a problem? Please describe.
No focus feedback is provided for invalid cells that are inside the table (cells that have border in red color). See video attached.

Note: The only invalid cells that provide a focus feedback are the ones located at the edges of the worksheet.

Describe the solution, feature, or improvement you'd like
Probably add the same active line that the invalid cells (located at the edges) use (see image)? or change the border color when focusing?

Describe alternatives you've considered

I believe this was done per design feedback, but I'm definitely open to rethink it!
