Strange, I can't reproduce it with any versions for now.

NI myself as I was able to replicate in my containers SDK removal patch.

Comment 3

[Jonathan Kingston [:jkt] he/him]

This is still reproducible for me, perhaps it is different but I have been working on a pure web extension version of containers here:

Get code:
- git clone [e-mail]:jonathanKingston/testpilot-containers.git
- cd testpilot-containers
- git checkout sdk-mamoth-breakage
- npm install

Test jpm:
- ./node_modules/.bin/jpm -v run -p profileWithXPICheckingDisabled -b nightlyPath

Test web ext:
- cd webextension;
- web-ext run -f nightlyPath -p profileWithContainersEnabled

Now in the jpm version you will see the asignment confim notification not show in the content window.

STR:
- Open a container tab
- Go to a web address
- Right Click "Always Open in This Container"

Expected:
There should be notification in that tab

Actual:
In the web-ext version the DOM nodes get injected and can be seen in the inspector but don't have the styles. There isn't any related difference to the CSS loaded in content from the JPM version.

Based on comment 3, CSS not working using web-ext.
