+# ADR 0010: Why do we need a fix in React?
+
+🗓️ 2023-07 · ✍️ [@igorwessel](https://twitter.com/igor_wessel)
+
+## Context
+
+In order to achieve a better DX with boolean props in React.
+
+## Problems
+
+Today (07/19/2023) the Stencil does not follow the HTML spec for boolean props, which caused problems in testing/styling because expected to not have a attribute in HTML when is false.
+
+Example:
+
+```jsx
+
+<AtomButton disabled={false} />
+
+// output in html
+
+<atom-button disabled="false" />
+```
+
+So it affects styles, and tests where the boolean attribute shouldn't exist
+
+Examples:
+
+```css
+// regardless if disabled is false/true will still be applied.
+atom-button[disabled] {
+  background-color: red;
+}
+```
+
+```js
+// regardless if disabled is false/true will throw a false-positive because expects the attribute does not exist.
+expect(atom - button).toBeDisabled()
+```
+
+## Decision
+
+After we consider the options:
+
+- Living with the problem for possibly in the near future react will offer better [support](https://github.com/facebook/react/issues/11347) for web-components.
+  > We can see [tests in a experimental branch here](https://custom-elements-everywhere.com/libraries/react-experimental/results/results.html)
+- We are already transpiling the web-component to React, could use a workaround.
+
+Based on these options, we decide to use workaround which will basically set/remove attributes after [occurs a update in component.](https://react.dev/reference/react/Component#componentdidupdate)
