Duplicate Backticks turn into [icode] inside [code] block

[Don Daniello]

Affected version

2.1.3

I am using XF 2.1.3 and I've turned off all addons, yet backticks take precedence over [code].
What's interesting is that here on this forum it doesn't happen. I had to specifically add those [ICODE] below to demonstrate.
I'm not sure if that's a different version of XF or different settings.

BB Code:

[code=sql]INSERT INTO bans (
`type`,
value,
expires,
added,
admin_id,
comment
)...[/code]


Expected rendering:

INSERT INTO bans (
    `type`,
    value,
    expires,
    added,
    admin_id,
    comment
)...

Actual rendering:

INSERT INTO bans (
    [ICODE]type[/ICODE],
    value,
    expires,
    added,
    admin_id,
    comment
)...

It doesn't happen here because it's already fixed for the next release:

Fixed - Markdown rendering triggering inside bbcode with 'Stop parsing BB code' set

XF\BbCode\ProcessorAction\Markdown::stashBbCodePlainItems has a hard-coded list, and doesn't check custom bb-code with advanced flags, where the 'Stop parsing BB code' makes sense to be skipped

@Chris D is there a patch we can apply earlier? We are having lots of malformed posts due to that problem.

Only workaround I can advise currently is to switch markdown processing off if it is problematic.
