Recently I'd want to report an issue to this issue tracker and tried to find the GitHub link but I failed, I only made possible to come here by a friend's hint.
Currently (at least in Firefox) one must:
However the step 3 is non-self-suggestible at all as user will presume that scrolling-down only show more changelogs instead of a link to GitHub. In my case I frustrated to end myself in the "Telegram Web" Twitter page since it's the only external link I could've found.

I would suggest that:
`Add these `lines in index.html
<link` rel="stylesheet" href="https://web.telegram.org/css/app.css"/>
<link rel="stylesheet" href="vendor/jquery.nanoscroller/nanoscroller.css">`
I'm sorry but this is an intended design. No plans to change it yet.
