Cannot show full file path for long symbol signature in Go To Symbol

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.63.2
• OS Version: Windows 10 Enterprise, Version 2019, OS Build 18363.1801

Steps to Reproduce:

1. Press Ctrl+T, type something to find symbols, it triggers a drop-down list. Each entry on the list has two parts, left is a matched symbol, right is the file path.
2. If the symbol part on the left is short enough, there will be some room on the right to show the file path (usually just incomplete file path). We hover the mouse over the file path, it'll display a pop up to show the full file path as below
   
3. If the symbol's signature is too long, there won't be room on the right to show the file path at all. So cannot hover the mouse over the file path, thus no way to tell which one is which as seen below
   
4. There should be a way to show the full file path, for example, change to be able to hover the mouse over anywhere of the entry to trigger the pop up to show the full file path

Notes to myself:

Perhaps once we have #138617, then we could have a nice rich visual hover of these symbols?

I get a native hover, isn't that sufficient?

I don't think the label gets a hover... only detail and description.

Easy fix: give label a hover
More interesting fix: use a custom hover and provide some nice rich visual (I'm thinking similar to the signatureHelp)
