Describe the bug

I am trying to filter on "sendMail" and then select the operation in Microsoft Graph

Expected behavior

I expect to see the POST operation under the sendmail node

How to reproduce

Open the Microsoft Graph v1 API in the VS Code extension.
Filter on "sendmail".
You will see the sendmail node but the POST operation is not displayed.
If you filter on schedule you will see a node that is called fvSchedule that shows a POST but the node getSchedule does not show the POST.

It also happens with "directReports" which isn't an action.

[darrelmiller]

Doh! It is a case sensitivity issue. As soon as a the search filter includes characters that are mixed in case in the tree, the operations stop appearing. Type "send" and you will still see the operations, type "sendm" or "sendM" and they disappear because "sendMail" has mixed case.
