Preselect value not updated properly after we dynamically change the datasource in mounted function

Case #1:

Since version 22.2.9 of the dropdown list control value gets cleared everytime we update the data source. Please check the following demo:

https://stackblitz.com/edit/vue2-vue-cli-16ndba?file=package.json,src%2Fcomponents%2FHelloWorld.vue

AllowFiltering property is crucial in this case.

In version 22.2.8 I cannot reproduce the issue.

Reproduction Steps:

  • Run the sample
  • You can see the issue

Expected Behavior: Preselect value should update properly

Current Behavior: Preselect value is not updated properly

Case #2:

When attempting to dynamically update a Dropdownlist component with different data sources and with the same index in the button click, the component's value fails to update as expected.

Sample:  https://stackblitz.com/edit/y5fqkj-rfyfve?file=index.html,index.ts



Replication Procedure:

  1. Run the sample.
  2. Click the button.

Expected: index 0 of new datasource should update to the component.

Actual: index 0 of new datasource is not updated.
