This needs the "KR: Real BCD" label

[Rob--W]

This data is incorrect. Please wait for review from webextensions people before merging BCD claims.

Sorry @Rob--W, this was important to land for our real values goal. Please feel free to open a follow-up PR and I will merge it!

[Rob--W]

I can currently not edit code (from my phone). I'll open a PR later ix nobody got to it before me.

The PR is straightforward - it would be this PR, except with 49 instead of 30.

Opened #24529

[danielhjacobs]

My other most recent two PRs are also meant to help with the real values goal: #24525 and #24527. With those merged and all the KR: Real BCD 🔑 Key Result: Eliminate true/null values and replace them with "real" values. PRs merged, the real values goal should be complete.
