### 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
