This is a fair compromise IMHO 👍
This PR would, unfortunately, introduce a regression to any consumer that is rendering

Is it even possible that there is such an instance existing and it's not broken in the same way as the test breaks?
Right now, a consumer may render

This is definitely not great and could potentially break existing usages.
I think this sounds like a good compromise. Do we have any usages in the Gutenberg core that will be affected? |

@ciampo Why would a button switch from having a tooltip to not having a tooltip while it's rendered in the DOM? What's the use case? Edit: I read the testing instructions, so the save button :) |
|
This is causing so much work to be done for buttons that never even show a tooltip. More often than not, buttons never have a tooltip. Why is this there even a tooltip option for a button, why is this not an optional wrapper component? |
FWIW, I would definitely not include a tooltip (and its floating-ui dependencies) if we were to design a Button component from scratch. Maybe in a v2! |

Fixes #56522
Requires #57202, #57878, #57975, #58125
What?
This PR tweaks the
Buttoncomponent so that it always renders theTooltipcomponent, even when a tooltip shouldn't be shown.It also un-does the temporary fix from #56502
Why?
This change is necessary to fix the issue described in #44735, where basically the element rendered by
Buttonwould be removed and re-added to the DOM any time theButtoncomponent switches from having to show a tooltip to not having to show it, and vice-versa.The fact that a new HTML element is re-created every time triggers a focus loss that can be very annoying, especially to assistive technology users.
How?
After some debugging, the issue seems related to the fact that React couldn't reconciliate the "with tooltip" and "without tooltip" version of the
Buttoncomponent without re-creating the whole button every time.To solve this, I decided to tweak
Buttonso that it always renders theTooltipcomponent.Note: this doesn't mean that the tooltip will always be shown, though — the original user-facing behaviour should have been retained by only passing props to the
Tooltipcomponent when needed.Testing Instructions

From #44735 (comment):
A similar approach can also be used directly in Storybook.
Also, make sure that in general, tooltips show on
Buttonwhen they are supposed to, and don't show when they are not supposed to.
