Overview: Boldness of certain white text within the CSS navigation bar menu changes after loading of the Google Map.
Steps to Reproduce: Simply load the page and note how the white menubar text looks when the page just opens versus a couple seconds later when the Google Map fully loads. (Resource: http://visionsecurity.jp/en/map.html) Not all the white text is affected. Only "Buy" & "Company" & "Contact" & "JAPANESE" lose their BOLD styling after the Google Map finishes loading. The animation on the map appears to be the trigger. The font styling bug does not appear on other pages in that same site.
Actual Results: "Buy" & "Company" & "Contact" & "JAPANESE" text lose their BOLD styling.
Expected Results: All the WHITE text within the same navigation bar should look the same before and after loading page animations (like Google Maps).
