When using extensions that use sidebar panels with content set with `sidebarPane.setExpression` an error is thrown.

Describe the bug When using extensions that use sidebar panels with content set with sidebarPane.setExpression an error is thrown.

To Reproduce Steps to reproduce the behavior:

1. Go to 'any extension that uses setExpression, e.g. https://chrome.google.com/webstore/detail/knockoutjs-context-debugg/oddcpmchholgcjgjdnfjmildmlielhof'
2. Click on 'Add to Chrome'
3. Load the dev tools with Ctrl + Shift + I
4. Load the extension dev tools by hitting Ctrl + Shift + I
5. See the error in the console.

Expected behavior Extensions should still work even after the v92 upgrade. It worked until v91.

@emilianionascu is this related to any of our documentation? This repo is only for docs work. If you've found a bug in Chrome it should be filed at crbug.com

@robdodson I'm not sure. It could be that the API changed and we're supposed to use setExpression differently. That is a documentation issue. It could be that the API itself has a bug and then it's not a documentation issue.

I believe I've hit this too with my extension: https://chrome.google.com/webstore/detail/sb-angular-inspector/lapcbklolihkkijaemmlbkpibgghhioh?hl=en

I thought it might be related to manifest 3, so I upgraded.

Still seem to be having an issue with setExpression.

OK, tentatively assigning to @awfuchs to take a look
