Wiki links in Preview are wrong

I noticed when writing relative links into a wiki page, links are placed beneath that page, when in reality that will not be the case. This led me to write broken links that worked in preview.

Example

Editing URL: https://github.com/MicroWrave/tri-plus-ger/wiki/Home/_edit
I write: [This is my link to](a-page)
I expect a link to: .../tri-plus-ger/wiki/a-page
Real link is actually: .../wiki/a-page
Preview link: .../tri-plus-ger/wiki/Home/a-page
So I wrongly write [This is my link to](../a-page)
which preview links to /tri-plus-ger/wiki/a-page
but actually links to /tri-plus-ger/a-page
