roslyn: After you dismiss "rename mode" for a symbol that is not a type definition, you never get asked to rename it again

When you change the name of a symbol, Roslyn offers to rename all references to that symbol to another symbol. This only works the very first time however, once you’ve dismissed it - you never get offered again to rename.

1. Create a new .NET Console Appliction (.NET Framework)

using System.Collections;

public interface IProjectConfigurationsService
{
}

class Program : IProjectConfigurationsService
{

}

1. Highlight IProjectConfigurationsService in Program : IProjectConfigurationsService
2. Type ICollection

– Notice the rename frame is around ICollection –

1. Press ESC to dimiss completion window and then ESC to get out of rename mode
2. CTRL+Z twice to undo the name and change it back to ‘IProjectConfigurationsService’
3. Type ‘ICollection’

Expected: To be back in “rename mode” Actual: Not in rename mode,

NOTE:

• If you do this to type definition itself interface IProjectConfigurationsService then this works correctly.
• While above is a good repro, it doesn’t really matter how you rename the symbol in the future - you never get into rename mode again for that symbol unless I close and reopen the file.
• It doesn’t have to an interface implementations - I could basically repro this whenever you rename a symbol that is not a type definition.
