Prerequisites

• I verified that this is not a filter list issue. Report any issues with filter lists or broken website functionality in the uAssets issue tracker.
• This is NOT a YouTube, Facebook or Twitch report. These sites MUST be reported by clicking their respective links.
• This is not a support issue or a question. For support, questions, or help, visit /r/uBlockOrigin.
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
• The issue is not present after disabling uBO in the browser.
• I checked the documentation to understand that the issue I am reporting is not normal behavior.

I tried to reproduce the issue when...

• uBO is the only extension.
• uBO uses default lists and settings.
• using a new, unmodified browser profile.

Description

ublock href-sanitizer scriplet does not show the desired behavior for links containing the % character in it. The same works as expected with the adguard addon and the filter rule.

Hello, when I apply the rule

forum.donanimhaber.com##+js(href-sanitizer, a[href*="/ExternalLinkRedirect"][href*="url="], ?url)

and click on the link at this address: https://forum.donanimhaber.com/mesaj/yonlen/158899898, it redirects to https://www.temu.com/goods.html?_bg_fs=1 and truncates the rest of the link. However, the link in this message works as expected: https://forum.donanimhaber.com/mesaj/yonlen/158901348.
I noticed that the links which do not work correctly contain the word 'html'.

it redirects to https://www.temu.com/goods.html?_bg_fs=1

It's a site issue, it's not properly encoding the URL.
