I'm seeing this behaviour in one of the websites I manage:
<link href="//fonts.googleapis.com/css?family=Abril%20Fatface:regular" rel="stylesheet" property="stylesheet" type="text/css" media="all" /><h1 style="color: #ffffff;text-align: center" class="vc_custom_heading home-title">Some title</h1>
As such, on a page with one H1 and five H2, I am seeing six calls for //fonts.googleapis.com/css?family=Abril%20Fatface:regular
The website is based on Wordpress and this behaviour is most likely dictated by the WPBakery plugin.
The question, however, is not a Wordpress or plugin support question, as my interest lies in whether such behaviour is normal in general (but perhaps not a best practice) or it's something that I must address to optimise the page.

so that you do need to bloat your WordPress with endless plugins, or you could even use Google Tag Manager, that way all scripts and styles are handled by Google.
