The DiscoTOC disappear in some users' view

[SkyLin]

The TOC disappears yesterday*, but it works fine on iPhone.
(* Works fine before yesterday)

I thought it’s due to the Chrome extensions, so I remove some for testing. However, it doesn’t solve the problem.

So I do more testing with different account on a same computer. Here comes the result.

Any idea how to solve this?

Thanks for help in advance.

	User 1	User 2
1. TOC in post	X	O
2. TOC in post with incognito mode	X	O
3. TOC in Composer	X	X
4. TOC in mobile	O	O

User 2:

Update info. after 10 hours.

Now the user 2 behave the same as user 1(desktop failed, iPhone works fine).

I will rebuild to see if this way solve the problem then.
