The specification states:

 ... Inert subtrees
  
     ... When a node is inert, then the user agent must act as if the node was absent for 
     the purposes of targeting user interaction events, may ignore the node for the 
     purposes of text search user interfaces (commonly known as "find in page"), and may 
     prevent the user from selecting text in that node. ...

All document modes (All versions)

Selection and find on a page are prevented from working when the page is inert because of a dialog.
