Feedback on #21334: Row actions are not always keyboard accessible

I’ve made two commits so far to address the fact that row actions (that is, edit/quick edit/trashTrash Trash in WordPress is like the Recycle Bin on your PC or Trash in your Macintosh computer. Users with the proper permission level (administrators and editors) have the ability to delete a post, page, and/or comments. When you delete the item, it is moved to the trash folder where it will remain for 30 days. under each post’s title) only show on hover. I have two questions regarding this that I could your expertise on:

1. In terms of CSSCSS CSS is an acronym for cascading style sheets. This is what controls the design or look and feel of a site., this is controlled by the visibility property. My understanding has been that visibility: hidden does not get read by screen readers. If this is the case, then we may want to use an alternative method for show/hide. Are these row actions currently in a state where they are useful to screen readers or are they better off not being read (for now)?
2. Right now the keyboard tabbing will only trigger them to show when in the same cell. Should this expand to whenever focus is within the row? I believe visually it is when hovering on the table row.

Thanks!
