'Forwarded URL renders the webpage in half the height as normal for a Flutter Web app hosted in Firebase
I have a firebase hosted Flutter Web application which is a game. Since the URL for the Firebase hosted site (https://jw-daily.web.app) is difficult to remember for users, I bought a domain name (joinedwords.com) and redirected the URL to the firebase hosted site.
Problem is that when I type the domain URL i.e. joinedwords.com, the website renders in only half the height like below:
However, if I type the original URL (https://jw-daily.web.app) in the browser, the webpage renders in full like below:
All that I have done is with my domain provider, I have set a forward with masking of joinedwords.com => https://jw-daily.web.app/
I looked up all the other solutions around why a webpage is rendering in half. However most of them are asking to make changes to the code and I don't want to do that since the original URL is working fine. Incidentally this issue is happening only on mobile browsers and not happening on desktop. In desktop, the website renders correctly regardless of which URL is typed.
Please suggest if you are aware of how we can solve this problem. Here is my index.html file.

Found an answer to the issue I was facing. Here is the link to the same: Bootstrap Responsive Design Fails with Web Forwarding
This is because you are using a framed redirect which essentially loads up the target website in an iFrame. Doing so loses any responsive capabilities. What you are best doing is changing your web forwarding method to actually forward to the new URL using a non-framed redirect. This will then properly load up the target URL in the users browser and all the responsive capabilities that go with it.
