[Q] stock browser won't let me delete gmail emails

view story

http://forum.xda-developers.com – I tried searching this problem on Google but the only solution that I came across was by either browsing gmail in classic or desktop mode on stock browser. I can't seem to delete gmail email in mobile version. when I press the recycle bin icon to delete an email, the icon turns blue to indicate that it has been pressed, but then it doesnt reload the page or delete anything. it just hangs.. since I am a frequent gmail user, I use dolphin browser instead and it works fine but I want to know what's causing the problem. btw I don't use gmail app. my issue here is accessing gmail on stock browser (HowTos)
