My tablet is a Galaxy Note, so I can get around this with the S-Pen (the menu shows when hovering the stylus over the screen). If I'm too lazy to get the stylus out or am on my phone, though, I hold my finger on the menu (Forums button, for example) until the context menu opens. Hitting back to hide the context menu leaves the navigation menu still open. Well... At least it works part of the time... Sometimes I just have to be really quick. Let go before the context menu opens, and quick pick what I want from the menu before the linked page loads.
/edit: I had brought this up to Dolby once, long ago, and he said that it worked if he just tapped the nav bar (or something like that - was a long time ago). I could never get that to work myself, though.
