[USER] Weird Title Rendering on Various Clients

[The Gnuserland]

Hi Geminauts,

I am trying to understand what got wrong with the document below, the 
very first title is not rendered:

gemini://gnuser.land/gemlog/draft/bug01.gmi

The "bug01.gmi" was started in Micro and finalized in Mousepad (Debian, 
XFCE4).

Than I copied all the content into Geany (Debian, XFCE4), removed some 
white spaces, and saved it as "bug02.gmi", and the title was formatted 
properly.

gemini://gnuser.land/gemlog/draft/bug01.gmi

A diff made to both files shows there is actually a **difference** a the 
very first line, but what is that?

diff -bZ bug01.gmi bug02.gmi
1c1
< # Title 1
---
 > # Title 1

Thanks!

TGL
