1820528 - id="..." links won't open <details> disclosure elements

Status: RESOLVED DUPLICATE of bug 1724299

(Core :: DOM: Core & HTML, defect)

Description

[Patrick C]

Attachment: example.html

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/110.0

Steps to reproduce:

link to
example.html#my_target
with

<details>
<summary>Topic</summary>
<p id="my_target">Details on topic.</p>
</details>

Actual results:

The details element did not open.

Expected results:

The details element should open (it does on chromium based browsers).

Workaround:

I don’t see any advantage in the details element not opening. Furthermore FF opens details elements when searching for strings so why not on #id links?

Moving to Core:General but I think this belongs somewhere in DOM

It looks like there's a WPT for this behavior: testing/web-platform/tests/html/semantics/interactive-elements/the-details-element/auto-expand-details-element-fragment.html

This looks like the Chromium feature page for this, with links to the relevant specs: https://chromestatus.com/feature/5032469667512320

https://wpt.fyi/results/html/semantics/interactive-elements/the-details-element/auto-expand-details-element-fragment.html?label=experimental&label=master&aligned claims Firefox passes. Is this issue obsolete and already fixed somewhere else?

Thanks for pointing this out. Yes, auto-expanding details have been implemented recently in bug 1724299. As of today, this only works in Nightly, but it will be available in Release 139.
