Tag works fine on mobile but not on laptop

Jun 10, 2019

So I heard about this tagging issue. I decided to test it out by responding to a notification on my phone with the site in mobile view instead of on my laptop. And I immediately noticed a difference. On my laptop(which is Windows 10 with the browser that I'm using being Firefox), when I hit reply under a forum post, the tag comes out as just text. But on my mobile phone, if I do that same exact procedure using the built in Google chrome browser on my android, it actually comes out as a tag. 

So for example, if I were to reply to Teodor Lontos, doing it on my laptop results in this:

Teodor Lontos "Reply to him"

and the only notification he gets is that of a reply to his comment

Doing it on my mobile phone results in this:

(@Teodor Lontos) "Reply to him"

And here, he would get not only a notification of a reply but also a notification of being mentioned.

I just put the parentheses there so that you could see that on my mobile phone, a tag results but it doesn't result if I do that same procedure on my laptop. This suggests that the issue is either browser specific(in other words, the fact that I am using Firefox on my laptop makes the tag come out as text) or OS specific(like it is an issue with Windows itself and doesn't affect Android or any other OS).
