Steps to reproduce the problem:
1. Open attached file (style_change_test.html)
2. Open Developer Tools window.
3. Under the "Elements" tab, click on the span element, so that the entire line is highlighted.
4. Click on the "Click Me!" button on the web page (the "Example Text" should turn blue).
5. Try one or more of the following:
	a) Under the "Styles" tab, untick the "color" property.
	b) Click on the coloured square ("color-picker"), change the colour, and press the Enter key.
	c) Click the name of the "color" property, press the Backspace key and then the Enter key.
	d) Click to the right side or underneath the "color" property, type in the name of another property (say font-size), insert the respective value (say 18px), and press the Enter key.

What is the expected behavior?
a) The example text colour should change back to black.
b) The example text colour should change to the selected colour.
c) The "color" property should be removed.
d) Another property should be added and effected.

What went wrong?
a) The example text colour does not change from blue
b) The example text colour does not change to the selected colour
c) The "color" property remains intact.
d) Another property is not added; the example text remains the same.

Step #3 is critical. The element must be selected/highlighted before the button is clicked, for the bug to be reproduced.
