Description

The Table of Contents (TOC), which is hidden under the LEFT PANEL, appears when the header has a long title.

You can check in https://projectreactor.io/docs/core/release/reference/metrics.html

Image

When the screen width is less than 1024px, the LEFT PANEL disappears, making the TOC more visible.

Image

If the screen width is less than or equal to 800px, the TOC disappears completely, and there is no issue in this case.

Why is the hidden TOC necessary?

Research direction
Investigate the CSS and JavaScript responsible for the Table of Contents (TOC) visibility on the documentation site, particularly at screen widths between 801px and 1023px. Look at the media queries and any JavaScript that toggles the left panel and TOC. The issue provides example URLs where the bug occurs. Check the repository's documentation source files (likely in a docs folder) for the relevant styles and scripts. The fix may involve adjusting the z index, display properties, or media query breakpoints to ensure the TOC remains hidden when the left panel is hidden.
