Strange behavior in markdown-mode

[mrkkrp]

Sometimes ace-link behaves strange in markdown-mode. It looks like in all cases it outputs the message:

ace-link: markdown-mode isn’t supported

However sometimes despite the message, links are opened just fine. Which is not surprising, there should not be any difficulties with opening links in markdown-mode given that normal URLs are already recognized in other modes. Other times the message is printed and indeed links are not opened.

This is disappointing because in that case I have to copy links manually and paste them in search bar of my browser.

My setup is essentially just this:

(ace-link-setup-default) ; use ace-link in various major modes

(global-set-key (kbd "M-o") #'ace-link) ; maybe ace-link-setup-default is not necessary 
                                        ; if I bind a different shortcut myself?
