Steps to reproduce

1. Open a Decision Table
2. Add a column using the mouse

Expected behavior

Either

• The button is shown on hover of the Table header and I can use it to open the edit menu
• It is not shown at all when interacting with mouse only

Environment

• Operating System: Linux x86_64 amd64
• Plugins:
• Execution Platform: DMN - Camunda 8

Additional context

No response

In the tool, we rely on :focus-within selector to display the button. We should use :focus-visible instead.

:focus-within -> a descendant has focus :focus-visible -> browser "thinks" focus should be displayed
