I can select type "Q_PRO" and then select the property snippet. It then expands as expected and sets the cursor to input the type.

But the boxes that indicated the inputs are not shown. And after typing the type, I'm not able to "tab" as usual to move to the next input. Instead the Snippet input is finalized.

More or less the same for QML snippets.

I didn't change anything (plugins etc.) since upgrading from QtC 4.4.
