Steps to reproduce:

1. Place your mouse over the area where the 2nd suggestion will appear (Single Line Input Example)
2. Type @W
3. Notice Skyler White's name is selected even though she's the second result
4. Press enter and Skyler White gets inserted

Expected behaviour:

Would expect Walter White to be the inserted mention since he is the top typed result.

Workaround:

Move mouse away before doing a mention
