This is a good first PR!
We should add some tests to cover #7036. They should cover both JavaScript and TypeScript support.
They can probably be added to test/fixtures.

</Menu>I'm running into an issue where I need to handle the event propagation for the escape key on my own. It's impossible to get around because it's hard-coded in the handleKeyDown callback.
To be specific, I have a Popper rendered (via portal) over the modal, and when a user hits the Escape key, I want to close the Popper, but not the modal.

I'm confused about whether onFocus/onBlur events should bubble in preact, like they do in React.
In this example using preact 10.0.0-beta.1 they don't bubble https://codesandbox.io/embed/5wxk9zk7lx
...whereas in the Preact repl they do bubble https://preactjs.com/repl
export default () =>(
<div onFocus={() => console.log("FOCUS")}>
<div>

Hi folks, I've tinkered a lot about MobX 6 lately, so I want to layout the vision I have currently
Goals
🧨 1. Become compatible with modern ES standards
Let's start with the elephant in the room.
I think we have to drop the support for decorators.
Some have been advocating this for years, others totally love decorators.
Personally I hate to let decorators go. I think

Current Behavior
The type ErrorMessage doesn't have an id property.
Desired Behavior
It'd be nice id?: string would be added to the type ErrorMessage and set on the outermost component that serves as error message.
Suggested Solution
Add id={this.props.id} to the outer component in ErrorMessage.
Who does this impact? Who is this
There is a difference in safegetzipfile method between xlsx.js & xlsx.mini.js.
One is missing replace(/^Root Entry[\/]/,"") so I get this error "Cannot find file [Content_Types].xml in zip" ev
Too wide (and falsy) segregation of GraphQL Types and Resolvers
The first example of this is new ObjectType in src/data/queries/index.js importing fields.
Fields should be taken in context of parent type, not as standalone information.
This can ensure some users that custom types cannot have own field resolvers which is false.
In fact, much of fields which can have own resolvers

I'm aware that this is a bug tracker and not a support system. But there is one place in the official documentation which puzzles me. I just wonder if react-redux team has decided to pick one implementation over another for a specific reason or else.
