[NTG-context] Text background starting in the middle of the last line of a page

[NTG-context] Text background starting in the middle of the last line of a page

[-- Attachment #1.1: Type: text/plain, Size: 1132 bytes --]

Hi,

I am facing two minor issues with text backgrounds, both demonstrated in
the example below:
* If the background starters in the middle of the last line of a page, the
highlight extends down the end of the page in a full horizontal line. (See
end of page 1 in the output.)
* It seems that characters extending into the margin are not highlighted.
(See ‘anim’ on page 2 in the output.)

Is there a way to change the behaviour of the text background to correct
the above two points?

```
\setuppapersize[A7]

\definetextbackground[highlight][
  background=color,
  backgroundcolor=yellow,
]

\starttext
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod
tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim
veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea
commodo consequat. Duis aute irure dolor in reprehenderit in voluptate
velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat
cupidatat non proident, sunt \highlight{in culpa qui officia deserunt
mollit anim id est laborum.}
\stoptext
```

Cheers,
Florent

It doesn't extend, but it's an overfull line, use

\setupalign[tolerant]

Thanks a lot Hans for your quick reply! I confirm that
\setupalign[tolerant] solves the second point.

I am still facing the first issue when moving the start of the highlight so
that it starts on the (updated) last line of the first page. Is there
something I am doing incorrectly?

```
\setuppapersize[A7]

\setupalign[tolerant]

\definetextbackground[highlight][
   background=color,
   backgroundcolor=yellow,
]

\starttext

velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat
\highlight{cupidatat non proident, sunt in culpa qui officia deserunt
mollit anim id est laborum.}
\stoptext
```

Cheers,
Florent
