1314048 - "Find in page" doesn't find text that's in un-opened HTML5 <details> elements

Status: RESOLVED DUPLICATE of bug 1724299

(Toolkit :: Find Toolbar, defect)

Description

[bugzilla.mozilla.org]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0
Build ID: 20161019084923

Steps to reproduce:

Tried out the new HTML5 elements <details> and <summary>.

First created a little demo:

<details>
 <summary>Click me to open details</summary>
 <p>Some details that are hidden by default, because &lt;details&gt; has no open attribute</p>
</details>


Then tried to find "attribute" using STRG+F.


Actual results:

Find did not find the word "attribute" within the page.

Then I opened the details block manually by clicking on "Click me to open details" and re-searched for "attribute".

Then FF found "attribute".


Expected results:

If the search term is contained in un-opened (details are closed by default) details blocks, those blocks should be opened (even if nested) so the search term is being found/highlighted.

Should also be the expected behaviour on mobile Firefox.
