* Adds sticky behavior to pinned page tools * Moves scroll indicator styles into a mixin shared by TOC and page tools * Replaces the 10px magic number in the TOC used to calculate the bottom padding with the @padding-vertical-dropdown-menu variable. * Increases the pinned TOC max-height per T319315 * Corrects spacing between bottom of sticky header and top of TOC after discussion with designer * Causes 43 visual changes in Pixel that include intentional changes and subpixel rendering changes associated with the `contain: paint` rule. Bug: T318169 Bug: T319315 Change-Id: Ica0c4e0de1825d37d8136b589a9bf5decc96855e
