Paypal banner blocks typography button on mobile

I'm using Firefox on a Moto G6. The "buy me a beer/coffee" link blocks the typography button at the top of all pages. The typography button is displayed, but trying to click on it activates the paypal link. This means I can't switch to dark mode and increase the font size, so I'm not able to read the book on mobile.

Your experience is valid. However the button isn't clickable even if I delete the donation button:

How the donation button is added :

typescript-book/header.html

Line 4 in 158eabf

    
           var content = '<a href="https://paypal.me/basaratali" style="display: block;text-align: center;"> Buy me a beer / coffee 🍻 ☕️ 🌹 <br><br><img src="https://img.shields.io/badge/Donate-PayPal-green.svg" alt="donate"><br><br></a>';

You can remove it in the rendered dom and see that the typography button still becomes unclickable even without the donate banner. Gitbook bug 🌹

There is no paypal banner anymore 🌹
