Steps to reproduce:
1. Open the Web Console

3. Continue typing (eg "document.all.__de")

The suggestions are displayed until they are selected.

Actual results: 
In some cases the options given are deleted, the pop up disappears.

Here's a patch that fixes the issue with a test case.

The problem was that console didn't consider prefix underscores as a valid characters in property names when it was constructing a prefix filter for cached entries but the server actor returned them correctly. For example when writing 'document.all.__d' the results came directly from the server but for term 'document.all.__de' the results were from a local cache of previous results. Due to the invalid prefix filter (it was 'de' instead of '__de') no cached entry matched the results.

The same thing happens with properties that start with '$$' so I decided to fix that case too.

looks good. Just a minor comment update required.

I would update the comment to say something like,

// Find the last non-alphanumeric other than _ or $ if it exists.
