Inputting the exact value not choosing the option when the value and display text are different

Prerequisites

• I have searched for similar issues in both open and closed tickets and cannot find a duplicate
• The issue still exists against the latest master branch of Select2
• This is not a usage question (Those should be directed to the community)
• I have attempted to find the simplest possible steps to reproduce the issue
• I have included a failing test as a pull request (Optional)

Steps to reproduce the issue

1. Create an select element with value not equal to the display text.

2. Call the select2 function, with tag function turned on Or 1+2. https://jsfiddle.net/rLmztr2d/237/

3. Input a value that is equal to the display text and press ,

Expected behavior and actual behavior

When I follow those steps, I see… A new tab created with value and display tag both equal to the input value

I was expecting… The option with the display text chosen, no new tab created.

• Google Chrome
• Mozilla Firefox

Isolating the problem

P.S. I have already found a way to hot fix the problem, but I hope select2 will fix it so that no more hot fix is needed. https://stackoverflow.com/questions/46361910/select2-error-on-tag-when-value-is-not-the-same-as-display-value/46362316#46395657

My mistake, I believe I misunderstood your issue. It sounds to me like this is actually a duplicate of #4610, then?
