element-web/src/Modal.tsx
R Midhun Suresh 91e84f7951
Upgrade to latest compound-web package (#84)
* Upgrade to latest compound-web package

* Use a custom render function for jest tests

This way we don't need to manually wrap our components with
<TooltipProvider>

* Pin wrap-ansi to fix broken yarn install

* Add playwright helper to find tooltip from element

and use it in the failing test

* Exclude floating-ui divs/spans from axe testing

This is rendered outside .MatrixChat by compound and contains all the
tooltips.

* Wrap outermost components with TooltipProvider

* Remove onChange and use onSelect for toggle

* Fix jest tests and update snapshots

* Use vector-im/matrix-wysiwig
