If you spell the name of a transform wrong, no steps are selectable.

When adding steps to the canvas, say "Table Output", if you spell the word a little wrong, no suggestions in the dialog box are able to be selected.

To reproduce:
1. We want to try to place a Table Output step on the canvas.
2. In the search box, type "Tablet" (the extra t is what shuts things down).
3. You'll see the "Table Output" step shown for selection, but will not be able to click it.
