By using git bisect I was able to determine the following commit broke the lightbar in ansiview, but only on the first page.

```
commit 8eef2dc8294a551009f2ee63b92aa14983b0b811 (HEAD, refs/bisect/bad)
Author: Rob Swindell (on Debian Linux) <rob@synchro.net>
Date: Thu Apr 25 23:00:46 2024 -0700
```

There is no highlighted bar after this commit.

Either that is it 'fixes' something that is now showing as broken within ansiview.

Thank you! Good find (and the bisection report saves me a lot of time!).

It appears to be the result of the change to `attrstr` (now called `strtoattr`) which stops parsing when reaching an invalid attribute character (but before would continue parsing, just ignoring invalid attribute characters).

So something in `tree.js` or one its dependent scripts must be setting an invalid attribute character. :-( I'll have to dig a little more later to find out why/what.

Full credit to Dan_C for spotting the issue. I did the laborious job of hunting down the commit.

Assignments of strings (that contain invalid attribute characters) to `console.attribute` most likely.

tree.js only includes funclib.js and that itself only includes sbbsdefs.js upon certain conditions.
Maybe it's another of the included files in ansiview.js ?
