QSS syntax highlighting incorrectly positions colour preview box

When editing QSS files in VS Code with the Qt Core extension installed, any lines using the color syntax will have its colour box rendered before the whitespace. See attachments for comparing the bug and expected behaviour (the latter is a mock-up).

Shorthand (#RGB) hex codes are also not rendered.

Testcase (test.qss)

QMessageBox {
    color   :        #D6D6D6;
    selection-background-color:      #008000;
    selection-color:      #fff;
}

This can be reproduced in a clean VS Code environment, on both the current release (v1.0.0) and pre-release (v1.1.0) versions of the extension.
