|
|
// calculate it manually so we can sticky things in the right places. We also
|
|
// target the headerText instead of the container to reduce jumps when scrolling,
|
|
// and to help hide the badges/other buttons that could appear on hover. This
|
|
// all works by ensuring the header text has a fixed height when sticky so the
|
|
// fixed height of the container can maintain the scroll position.

// The combined height must be set in the LeftPanel component for sticky headers
|

// to work correctly.
