Pressing enter to open select2 is making two data source calls 2

[oazcurra]

I've to open a new issue since I cannot re-open the previous one (#5256).

Here is the link to a jsfiddle to test it https://jsfiddle.net/oazcurra/qcayogxp/28/

You need to open browsers console to see network calls and then:

• focus on the input text and press tab on the keyboard to move to select2
• click enter to open select2 component.

You will see that 2 requests are made to the data source.
