Why M-x highlight-regexp does not work after sort in tabulated-list-mode?

[Jean Louis]

I am trying to understand this. Here is the problem, step by step:

1. {M-x package-list-packages RET}

2. {M-x highlight-regexp RET gnu RET RET} this will highlight word
   "gnu" everywhere

3. Click to sort the list by column like "Version"

4. Highlights are lost, and I can understand that. 

   But {M-x highlight-regexp RET gnu RET RET} does not work any more
   at this point.

This was already on the mailing list, but I have forgot what to do to
remedy this.

I do need to make sure that some highlights appear after sorting of
tabulated-list-mode.

Does anybody have clue why is this happening?
