Google Maps uses Roboto for it’s fonts, and because it’s not an
iframe the Roboto font stylesheet needs to be imported if the site isn’t using it. The problem with this is that it also imports the stylesheet even when the site already has Roboto. Not only that, but the stylesheet is injected at the top of the
head, meaning that it will override whatever Roboto fonts the site is already using. In my case, I was using the font weight 900, which Google Maps doesn’t use. This meant that all my 900 weighted fonts would adjust down to 700 once the maps initialised.
People have been bringing this issue up for years, since at least 2014, and unfortunately Google have been effectively silent on it.
Thankfully there is a fix available on StackOverflow. Place the code below just before the line to initialise the maps such as
