QWebKit also seems to have the same problem as follows,

# viewport meta tag tests that fail on the bot for yet unknown reasons
fast/viewport/viewport-6.html
fast/viewport/viewport-45.html
fast/viewport/viewport-58.html

[Kenneth Rohde Christiansen]

Here are the expected results from Opera.

fast/viewport/viewport-6.html
Expected values:  width=200, height=220, initial-scale=1.6

fast/viewport/viewport-45.html
Expected values:  width=3200, height=3520, initial-scale=0.1

fast/viewport/viewport-58.html
Expected values:  width=3200, height=3520, initial-scale=0.1

Reproduced with r79438 and Qt 4.7.1 in the tester virtual machine

Curiously, in my Linux 64bits and Qt 4.7.x the three tests pass.

Is this correct in comparison with other platforms?

[Igor Trindade Oliveira]

Yeah,

Just gtk is testing viewport tag and it works with the new expected result.
