Unable to press key multiple times to cycle through options with that letter in form select.

[harrington101]

When using the materializecss formSelect feature to convert an html select element into a materialize select element, the user cannot press the same keyboard key multiple times to cycle through entries that start with that letter. For example, I have a list of countries with United States at the top. The user should be able to press U once and select United States. The second press of the letter U should take the user to the next entry in the list that starts with the letter U (skipping Albania, Canada, Denmark, etc. and selecting United Kingdom). Instead it does nothing.
