A couple of issues around the node autocompletion search are also fixed in this PR

1. When the user enters some text in the search bar and clears it, the window should show the initial list of all the autocompletion elements for that port
2. The tag dictionary that is being used in the Search API contains a list of all Dynamo nodes that share a specific tag. So when the SubsetDictionary was being built, if any one of the nodes from dictionary match the subset list, the whole list of nodes that share a specific tag was returned. This would generate extra results(which were not a match) when some particular text was entered in the search bar. To fix this, we match the subset list with the returned search results in the end. I will add a gif to show the difference in the results.

After this PR:

Hi @reddyashish . I think this is a good approach, however you might have to make some changes to the tests. If I remember correctly, in my original PR I had to change a test to make it close the window twice.

Also, does it work so that if you select a node, the dialog still closes automatically. That would be important for usability, not sure if you could add a test for it.

Yes changed the test accordingly. Regarding the second question: when you select the node, the dialog closes automatically. I think we will need a UI automation test for that.

Merging this.
