Slider appears when hovering for code annotations

[snhansen]

Bug description

When hovering on a code annotation and the corresponding code is highlighted, there is a slider appearing at the bottom like this. Perhaps the highlighting is a tad too wide?

This is using Quarto v. 1.4.90 on Windows.

Minimal example:

---
format: 
  html:
	code-annotations: hover
---

```{r}
test <- mtcars # <1>
```
1. Annotations

I am not able to reproduce this on MacOS Safari or Chrome. It may be browser/platform specific and could also be affected by any other CSS styling or themes in play. Can you share a little more info about where you see this happening?

@dragonstyle: It's triggered by all code annotations when hovering is enabled. I tried Firefox, Chrome and Edge, and the slider appears using all of them. I've uploaded the compiled minimal example to here https://biostat.au.dk/stefan/test/test.html, so you can see if it appears on your browser.

I haven't used any custom CSS styling, it's literally just the code from the minimal example above.

Very odd- I'm not seeing that when I view the deployed page. Perhaps OS matters? I'm on MacOS...

@dragonstyle: Very odd. I just checked with a Mac myself, and I'm not seeing it there either. But it's definitely present on Windows 10. Firefox on my Android phone has it briefly when clicking the annotation number, but disappears hereafter.

Ok I can take a look on a Windows machine, thanks for helping me narrow it down!

I can confirm I'm seeing it on windows too!
