On this page there are 2 event listeners listening to #click.
The first event listener is slow and unimportant, the second one a fast and important
When clicking the button the first and slow event lister will fire first and the second wil have to wait
This will cause an INP score of at least 1000ms
The faster way to do this is by wrapping your slow function in a 0ms timeout. This will yield to the main thread before executing this function. The 2esonc, important function does not yield to the main thread and is executed immediately
