@valbooth28 thanks for the PR! Made a few updates:
- Remove the $FlowIssue - see Common spread pattern leads to "exponentially large number of cases" errors facebook/flow#8186 (comment)
- Updated the docs to include the
objectFitprop - Added tests to ensure objectFit gets rendered
Also know that with every flow issue, we require the exact exception, so instead of something like // $FlowFixMe, we should write // $FlowFixMe[prop-missing]. See gajus/eslint-plugin-flowtype#453 for the request to make this an ESLint rule

@AlbertCarreras / @jennyscript fyi - a pattern we might see more often when we spread on a component. It's pretty verbose but better than adding a $FlowIssue / $FlowFixMe: facebook/flow#8186 (comment)
The { ...null } seems odd but it's what we have to do to make it work with exact types

objectFill as a propTypeobjectFill as a prop
Background
When Story Pins started using the Gestalt
Videocomponent for MP4s (experiment gated), employees noticed that the "poster", or placeholder while the video loads, was being displayed distorted.Repro

Screenshot for emphasis.
Changes
Setting the style as 'object-fill: contain
seems to fix the issue, so this PR adds the specificobject-fill` part of the style as an optional prop.Test Plan
Internal e2e testing confirms this will be a fix, and you can locally observe the style is passed correctly:
