-e: when you select an animation clip it is shown in the dopesheet in the Animation window but the sprites are not always shown when switching between animation clips

-repro:
--open attached project
--open Animation window
--select on of the animation clips for the cat
--expand the clip in the dopesheet to show the sprites
--now select the 2nd animation clip
--NOTICE the sprites are not shown in the sheet
--select the clip in the sheet
--notice the sprites are now shown in the sheet (see GIF below)

-this functionality seems new in 5.5 (in 5.4 you can't switch clips like that)
