Please fill in this template.

• Use a meaningful title for the pull request. Include the name of the package modified.
• Test the change in your own code. (Compile and run.)
• Add or edit tests to reflect the change. (Run with npm test YOUR_PACKAGE_NAME.)
• Follow the advice from the readme.
• Avoid common mistakes.
• Run npm run lint package-name (or tsc if no tslint.json is present).

Select one of these and delete the others:

If changing an existing definition:

• Provide a URL to documentation or source code which provides context for the suggested changes:
  • React 17 release changelog
  • unstable_expectedLoadTime PR
  • startTransition PR
• If this PR brings the type definitions up to date with a new version of the JS library, update the version number in the header.
• Include tests for your changes
• If you are making substantial changes, consider adding a tslint.json containing { "extends": "dtslint/dt.json" }. If for reason the any rule need to be disabled, disable it for that line using // tslint:disable-next-line [ruleName] and not for whole package so that the need for disabling can be reviewed.

👋 Hi there! I’ve run some quick measurements against master and your PR. These metrics should help the humans reviewing this PR gauge whether it might negatively affect compile times or editor responsiveness for users who install these typings.

Let’s review the numbers, shall we?

react-dom/v*

Comparison details for react-dom/* 📊

	master	#49152	diff
Batch compilation
Memory usage (MiB)	118.2	125.7	+6.4%
Type count	27087	27065	0%
Assignability cache size	6581	6578	0%
Language service
Samples taken	434	422	-3%
Identifiers in tests	434	422	-3%
getCompletionsAtPosition
Mean duration (ms)	655.6	650.7	-0.8%
Mean CV	8.0%	8.0%
Worst duration (ms)	851.5	911.6	+7.1%
Worst identifier	fragment	rootElement
getQuickInfoAtPosition
Mean duration (ms)	655.0	654.5	-0.1%
Mean CV	8.9%	8.9%	+0.2%
Worst duration (ms)	906.9	854.4	-5.8%
Worst identifier	renderIntoDocument	createElement

It looks like nothing changed too much. I won’t post performance data again unless it gets worse.
