Description
Remove the
isLoading
state variable in theuseWebviewContents
hook and return it as the length of the fetchedcontents
so if the contents object has no keys, it means that the contents are still loading.Context
After the migration from React 16 to React 18 the
useWebviewContents
hook was not working as expected because theisLoading
variable was being set to false before thecontents
variable was set in the state so the webview was trying to access to an emptycontents
object.Testing
