Update 2022-01-06 It appears this is no longer happening. I noticed today that after making an edit to tags there is no console log statement like Navigated to https://.../edit-tags. Maybe there was an errant header on the response, and that is no longer present?

It appears this issue from 2018 has started happening again. It happens for me on the Code Review SE site.

When editing a post's tags today (directly, via the Edit tags link), the tag edits are successful, but instead of returning me to an updated page, the browser shows a JSON response.

It happens in various environments, including Mobile Chrome 96.0.4664.116 on iOS, macOS Chrome version 96.0.4664.110, macOS Safari 15.1, Windows 10 Firefox 94.0.1 64 bit.

On the initial page load, I see these errors in the console:

The resource at “https://ad.atdmt.com/i/img;adv=11002245653149;ec=11002245685555;adv.a=3569326;c.a=26183389;s.a=5853708;p.a=318112380;a.a=510893068;cache=1364153242;” was blocked due to its Cross-Origin-Resource-Policy header (or lack thereof).

Then after making the edits to the tags:

In Firefox Developer Edition version 96.0b10 (64-bit) a similar error is observed in the console:

Uncaught TypeError: can't access property "each", e is undefined

with an identical stack trace to the previous trace.

    Sorry for the edit + rollback, had to try - I wasn't able to reproduce this on Windows 10 Chrome ver 96.0.4664.110 - Here's my point of view when I did (nothing special just me changing the tags and reverting) I wonder what the deal is.

    @rene something like freebies: ["pizza", "ice cream"] would be nice...

    Anything in the browser console, e.g. errors, network errors? Saving tag edits with Firefox 97.0a1 (with 100.0 user agent string) on Stack Overflow, just now, works just fine for me. Jan 5 at 19:09

    @SebastianSimon I have edited the post to include errors from the console.
