Textbackground overlapping

Textbackground overlapping

[nico]

Hello,

When the backgrounded stuff starts from one page up to the following, it  
doesn't take care about the bottom footnotes, so that they are covered by  
the background.

Here is a small example:

\definecolor[ScreenGray][s=.95]
\definetextbackground[grayback]
     [background=color,
      backgroundcolor=ScreenGray,
      frame=on,
      strut=yes,
      width=broad,
      location=paragraph,
      framecolor=ScreenGray,
      leftoffset=\topskipgap,
      before=\blank,
      after=\blank,
      align=right]

\starttext

A footnote\footnote{Covered by the background, right?}.
\input tufte
\input tufte
\input tufte
\input tufte

\starttextbackground[grayback]
\input tufte
\stoptextbackground

\stoptext

Regards,
BG

Ah, yes, there's no more overlapping for both test cases.

But I've seen a side effect of this setting. It appears rarely, and I had  
difficulties to reproduce it. So, please find attached the cut-and-pasted  
buggy page to have exactly the same placements.

The problem is that with this setting the blank spaces around titles or  
paragraphs is a bit greater than it was. It's not an issue by itself, but  
then the text sometimes overlap the bottom footnote. Note that there's no  
textbackground involved in attached the case. It is defined only to  
activate the behaviour via the \enabletextarearegistration call.

Here is a simple test case able to reproduce the problem (same behaviour  
with context live). Seems related to some vertical stretching stuff in a  
page.

\chardef\kindofpagetextareas\plusone
\setupcolors[state=start]
\setupwhitespace[medium]

% needed to activate the buggy stuff...
\definetextbackground[listing][background=color]

\starttext

\input tufte\footnote{A footnote}

blah

blah

blah

blah

blah

\section{Section}
\input tufte

\startitemize

\stopitemize
