Setting right:0 after sticky positioning does not take effect

Introduction

 .action {position: sticky;bottom: 20px;right: 0;}

After the above code is set, the element does not move to the right but is still on the left, but setting left is useful

Workaround

 .action {position: sticky;bottom: 20px;left: 100%;transform: translateX(-50px);}

This solves the problem of leaning to the right
