Today
- Let's look at what it took to get the moz-label working like we wanted
- Now let's write some tests!
InspectorUtils.getChildrenForNode($0, true, false)[1]- ^-- where \$0 is the label element
- Let's write a mochitest-chrome test that checks that center cropping actually works
- dom/html/test/forms/testchromelabelcentercropping.html
- We expect center cropping to work when crop="center" and value="some string" and text-wrap: no-wrap and max-width applied.

- Let's write a mochitest-plain test that checks that center cropping does not work for plain HTML documents
- dom/html/test/forms/testcontentlabelnocenter_cropping.html
