Description

Steps to replicate the issue (include links if applicable):

Have a CommunityConfiguration schema with PageTitlesControl
Enter a value (e.g. Template:) to trigger the dropdown of values
Select a title (e.g. Template:CN)

What happens?:
Template:CN is added as a chip. The text Template: remains in the input

What should have happened instead?:
Template:CN is added as a chip. The text Template: disappears.

T388567: "[Vue warn]: Attempting to mutate prop "inputValue". Props are readonly." when using NamespacesControl seems related

Some quick poking at this found another "non-Vue" hacky way of dealing with this :3

        },

Additional note - a user should be able to dismiss the input, when no selection was made, by clicking outside of the suggestion drop-down list.
Current behavior:
Template: input will be added even if a user doesn't select a template from the drop-down suggestions:

a user types Template: and sees the drop-down list of suggestions
a user decides not to select anything and clicks outside the drop-down selection list to cancel the action of typing a template name
Template: will be entered and a user needs to delete it by clicking on x or manually delete the input before clicking outside the drop-down list

Checked on testwiki wmf.14 - the issue in the task description is fixed, i.e.

What happens?:
Template:CN is added as a chip. The text Template: remains in the input

Note:

There are couple of usability issues, including the one mentioned in https://phabricator.wikimedia.org/T398428#10969829
it's possible to add an invalid input and only after publishing step, a user will be informed about a mistatke:
