Component: p-autoComplete multiple=true sometimes causes adding different/multiple values if one of them is a prefix of another

[malciin]

Describe the bug

Hello,

I've noticed that <p-autoComplete [multiple]="true" ... /> sometimes causes adding multiple values if one of them is prefix of another, and sometimes causes adding prefix value only rather than selected:

chrome_GMhZgo5KUC.mp4

(notice "test" was added rather than "test-1", and later both "test" & "test-1" were added)

To anyone that may have the same issue, the temporary workaround I've came up with is to use suggestions as an objects with prefixed label & custom ng-template:

Hi,

So sorry for the delayed response! Improvements have been made to many components recently, both in terms of performance and enhancement. Therefore, this improvement may have been developed in another issue ticket without realizing it. You can check this in the documentation. If there is no improvement on this, can you open a new issue so we can include it in our roadmap?

Thanks a lot for your understanding!
Best Regards,
