fix(checkbox): incorrect color for disabled indeterminate checkbox

crisbeto · crisbeto · commit 807a22761c86 · 2018-12-11T22:47:42.000+01:00
When we were implementing the new Material Design spec, [we based our checkbox state off this design](https://camo.githubusercontent.com/293e382a98c90eb68f6e537a714379e843493dd0/68747470733a2f2f73746f726167652e676f6f676c65617069732e636f6d2f737065632d686f73742d6261636b75702f6d696f2d64657369676e25324661737365747325324631374173385659376a4c4b4f53346e443170794e39343539667168386c65724b7525324673656c656374696f6e636f6e74726f6c732d636865636b626f7865732d7374617465732e706e67) which shows selected disabled checkboxes to be greyed out, whereas indeterminate disabled checkboxes having a slight opacity. After checking with the MDC team, the above-mentioned designs are incorrect and all disabled checkboxes are supposed to be grey. Fixes #14415.
