1253798 - A text file loaded in a frame does not word-wrap.

Status: UNCONFIRMED

(Core :: Layout: Images, Video, and HTML Frames, defect)

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160301003640

Steps to reproduce:

Using the below frameset code, I loaded a text file into a frame (see last frame).  

<FRAMESET rows="60, *">
  <FRAME src="header.html" frameborder="1" name="header" noresize="noresize">
  <FRAMESET cols="70, 250, *">
  <FRAME src="dir.html" frameborder="1" name="directory" noresize="noresize">
  <FRAME src="" frameborder="1" name="filelisting">HELLO!</frame>
  <FRAME src="/text/3.txt" frameborder="1" name ="content">
</frameset>
</FRAMESET>


Actual results:

The text in the text file frame is not word wrapped.  I have tried multiple text files to make sure it isn't a problem with a specific file.  All text files I've tried have not word-wrapped)

When I open the file directly (Ctrl-O), it will properly render the file with word-wrapping.

Also - if I am viewing the frames and then right-click the frame with the problematic content, then select "View only this frame", it will open the files as a single page, and then it will correctly word-wrap, just as if I had opened the text file directly.


Expected results:

The frame should word-wrap the file in the same manner a non-frame text file word wraps.

The plain text document has this markup:

<link rel="alternate stylesheet" type="text/css" href="resource://gre-resources/plaintext.css" title="Wrap Long Lines">

both when loading the document directly, and when embedding it in a <frame>
inside a <frameset>.  When loading it directly, "View -> Page Style -> Wrap Long Lines"
is selected by default.  When loading the <framset> the "Basic Page Style" is selected,
the "Wrap Long Lines" is there (but unselected).

I suspect this is working as designed, although I agree it might be confusing.

It might be better to just always wrap plain text documents (i.e. make the above
style sheet the default), and then provide the "wrap/unwrap long lines" function
only in View Source instead (which we already have, on the context menu).

Do any other UAs have a "wrap/unwrap long lines" feature for plain text documents?
If so, in the main UI and/or in View Source?
