I expected it to work, but somehow the map fails to show up. After some digging, it seems that the map fails to realize it height in the tab page if the tab page is not initially active. The solution is to add style="height:100%" to the <div class="tab-content"> so that it becomes like <div class="tab-content" style="height:100%">.
