Auto link complete not so well.

[Latisha19]

Generally, use <> with link "https://example.com/" can be an auto link, which will become markdown as "[ https: // example.com/ ]( https: //example.com/ )".
But if I use those links start without "http", auto link will fail.
For example, <chrome: //flags/> will become " [ chrome: / / flags / ] ( ) ", display in "chrome: //flags/", missing href.
What should I do?
Even I tried change to common markdown link "[chrome: //flags/ ](chrome: //flags/ )", href not displayed also.
Thanks for any advice, and sorry for many spaces inside link name.
