Really nice work! Works for me — toolbar popovers open down and to the right, but the centered-below-control-point gradient popover opens down and center: Thanks for this fix! 🚢 |

Looks really good. Code seems solid.
I noticed a potential issue—in the testing environment (localhost:8889 when using wp-env), the 'Gutenberg Test Plugin, Disables the CSS animations' plugin is used to disable animations. It makes puppeteer end to end tests more stable, since that library doesn't do auto-waiting like playwright does.
In this PR popover animations still seem to be active.
Good find! I'll have a look and report back (also curious to see if this issue affects other |

As I suspected, all @talldan , we could treat that as a separate issue and move ahead with this PR — what do you think? |

What?
Tracked in #42770
After the regression introduced by #40740, this PR aims at restoring (and improving) the
Popover's opening animationWhy?
#40740 introduces a few big changes to
Popover— in particular, it introduced a newplacementprop (that should replace the legacypositionprop). Alongside theplacementprop, #40470 introduced two new functions:positionToPlacement: a function to "convert"positionvalues toplacementvaluesplacementToAnimationOrigin: a function to associate an animation origin, given theplacementThis refactor caused the popover to animate unexpectedly (i.e. from the from animation origin (example).
Furthermore, as I looked into solving this issue, I noticed that
Popoverstill relied on theanimatecomponent, which was supposed to be deprecated already some time ago (see #27390).Finally, I also noticed that the
Popoverwas animating even when in its expanded mode, which is supposed to occupy the full screen on mobile — I believe that animating a piece of UI as big as the whole screen with a translate/scale animation could be excessive.How?
framer-motion(instead of theanimatecomponent) for thePopover's animationanimatecomponent:0.1scubic-bezier(0, 0, 0.2, 1)xandyaxis)0to1opacity)animateproperty, the popover won't animate when in its expanded state (on mobile). This change was caused by two reasons:placement— even if the placement isn't really taken into account in the expanded state (the popover is full screen)placementand/or is less overwhelming visually.placementToAnimationOriginlogic, using a lookup table instead of hard-to-read logic for the animation originpositionToPlacementandplacementToAnimationOriginto a separateutils.jsfilepositionToPlacementfunction and the variable parts of theplacementToAnimationOriginfunctionTesting Instructions
For ease of debug, the animation duration can be changes like so:
Storybook
Open Storybook and play around with the
Popoverexamples. In particular:placementvalue, the popover animates from the correct animation originanimateprop is set tofalseexpandOnMobileprop is set totrueand the popover is rendered in mobile viewports (even if theanimateprop is set totrue)prefers-reduced-motionflag is set by the user (even if theanimateprop is set totrue)In the editor
Do a sanity check across the editor and make sure that the popover behaves (and animates when necessary) as expected
Known issues
#42770 has a list of known issues.
Specifically to testing for animation origin, it is possible that the
positionToPlacementfunction introduced in #40740 is not converting the position 100% correctly. For the sake of this PR's scope, we should focus on theplacementto animation origin logic (thepositiontoplacementlogic can be tackled separately).Screenshots or screencast
