Error "zed: @brackets token returned but no bracket defined as: )]" when pasting wide text

[philrz]

Repro is with Zui commit f1aef59.

The attached Zed ciphers.txt includes a very wide line which I assume is the essential ingredient in this repro. As shown in the attached video, when I paste it into the editor, a large stack dump appears.

A paste of that same dump:

As far as I can tell the program still made it in ok, and I also checked on the GA Zui v1.7.0 release and the error only shows up in DevTools. Therefore this may not be urgent to address since it may not be user-impacting.
