This issue is not Front-End Related

**Describe the bug**

I am using the dcc.Dropdown with a list of over 5000 stock ticker symbols.  If I select any letter besides A, I am presented with all of the stocks that include that letter, not all of the stocks that begin with that letter.  It is therefore impossible to access the stock I am looking for without typing it out entirely, or using the scrollbar and manually scrolling down to it (required for 1 and 2 character symbols).  For example (screenshots), by typing M, I am offered AAMC, AAE, ABM, and 349 other symbols before getting to the one I want M (Macy's) and even hard-typing M (Enter) returns AAMC, which is why I this should be considered a bug and not a feature request.

**Expected behavior**

It would be expected that a dropdown searchbar prioritize front matches before body matches.  Body matches are nice, but most dropdown bars I've used only return front matches and ignore body matches.

**Screenshots**

Screenshots are attached as well as a file including my list of stock symbols to use as labels
