### Describe the bug

Data Annotations StringLength for client side validation of HTML Select isn't working properly. After some testing, it looks like the client side validation thinks the length of an HTML select value is always 1 (assuming something is actually selected). All server side validation is working fine, but the client is stopping it.

I realize this an odd use case. This only comes up because I want the property to have an exact length and I use it for HTML Selects on the front-end. So I decorated it with `[StringLength(9, MinimumLength = 9)]` and the client side validation stops it thinking it has a length of 1.

### Expected Behavior

I expect the client side validation to properly evaluate the length of a value even though it is in an HTML Select.
