Strange TOC behavior after autohiding.

[RegalPlatypus]

Discussed in https://github.com/quarto-dev/quarto-cli/discussions/1904

^{Originally posted by **RegalPlatypus** August 15, 2022} When generating an HTML report I like to display graphs side by side using the ```layout-ncol``` argument. This often requires me to increased the column width using ```column: page``` or similar. When you scroll to that point, the toc hides ([as it should](https://quarto.org/docs/output-formats/html-basics.html#table-of-contents)). However the toc behavior is usually different once the autohide has been activated. In the given example (viewed in Chrome) the toc immediately re-hides as soon as a user scrolls up or down on the page. The title of the first chapter containing the first ```column: page``` argument remains forever blue as though it is the current section being viewed, regardless of whether or not that is true. In my actual report, all toc levels >1 collapse and will never expand again so that the ```toc-depth``` effectively becomes 1. *Note:* For the example below I had to remove the ticks before and after the plot code chunk. It didn't like having a code chunk within a code chunk. ``` --- title: "Example Report" author: "John Smith" date: "1/1/2023" format: html: toc: true toc-location: left anchor-sections: false number-sections: true smooth-scroll: true self-contained: true output-file: "example.html" --- # First Chapter Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

I believe this issue should be fixed in our current pre-release. A pesky JavaScript error after hiding would cause subsequent JavaScript to fail.

Let us know if this gets you back up and running....

I downloaded and installed 1.0.38 (coming from 1.0.36). RStudio was closed during the install. I reopened my project and rendered the document, but unfortunately the bug is still there. Any further info I can give to help out?

(P.S., is there a way to view your current Quarto version from within RStudio?)

You need the pre-release build for v1.1 which you can get from here: https://quarto.org/docs/download/prerelease.html

@dragonstyle Looks like that did the trick! Thank you for pointing me in the right direction and, generally, for everything you folks do!
