Description

Clicking an anchor link linked to an emoji heading redirects only to the page (instead of the specific linked heading).

Steps to Reproduce

1. Add a title as unicode emoji
2. Insert an emoji via unicode characters, eg, copy and paste these 👹👺) only heading on page1, there should be no text in 
3. Copy the anchor link pointing to the emoji heading
4. Paste the anchor link into another page (page2), and publish the page
5. The anchor link will display in URL-encoded characters (even after publishing), and when clicking the link, the browser will redirect to page1 (but not the correct anchored section)

Sample anchor storage format:

<p><ac:link ac:anchor="%F0%9F%A5%B6-%F0%9F%91%BD%F0%9F%91%BD%F0%9F%91%BD"><ri:page ri:content-title="🥶" /></ac:link></p>

Expected Results

On clicking the anchored link, Confluence will redirect the browser to the respective anchored heading (and section).

Actual Results

On clicking the anchored link, Confluence redirects the browser to the page containing the anchored heading, but not to the anchored heading.

Workaround

Including text to the headings before emoji character will allow the anchored links to operate normally.
