s u b s t r($a,0,1)Substr in [code] section bug out? [possibly my own browser]

In summary, when attempting to preview a post containing the string "substr", the browser throws an error. This error persists even after trying to post the post without previewing it.

Can confirm. Putting the s back into the below causes the "Oops" dialog when I attempt to preview - Firefox on Android.
Code:
subtr($a,0,1)- #3

Code:
substr($a,0,1)works ok for me

When I attempt to preview this I get:Greg Bernhardt said:
If I attempt to post without preview, I get the same until removing the s.
Same if attempting to Save after edit.

Same problem here. Firefox on Ubuntu.
It's actually the string substr() that creates the bug. With or without characters within the brackets; within BBcode or not.
(I actually inserted a non-printable character between the s and the u to be able to publish this post)

It looks like I can preview a post containing the forbidden word once (in CODE tags or not), then get the error on anything I try to post (containing the string or not) on a subsequent try. Refreshing the page resets it. Did you try previewing more than once, @Greg Bernhardt?
I'll try on my laptop this evening and see if the browser console says anything - don't think I've got a console in 'Droid Firefox.

I checked the console and it is a Cloudflare problem:
Followed by an HTML page (yes, in the console) that reads (error set at core-compiled.js:3:1515):
I was unable to paste the actual HTML code as I was getting another console error:

I've made an adjustment to a CF rule. Can someone try again?

@Greg Bernhardt same issue here with some combinations of "c h a r ( )".
As above the proper fix is for Zenforo to change from Content-type: multipart/form-data to application/json, otherwise you will be patching CDN filter exceptions for ever (or can you just remove the filter altogether: I can't imagine Zenforo is vulnerable to script injection in 2022)?
