Hi @bouaik,
Thank you for this great contribution! 💪

I can confirm that the Products and Inventory pages now have the correct menu highlighting:

I couldn't check the Roles page because it wouldn't load on our staging servers due to a timeout error (I opened #11976). Probably there is just too much data to be displayed in that case. However, that page is only for super admins and not critical, so we can go untested with that one.

Bottom line: It's working great! I couldn't spot any regressions or issue with your PR. Excellent!
It's ready to get merged! 🎉
Thanks again! 🚀
