Reproduction steps:
1. Open user's attached project "CursorTooBig"
2. Go to Window > General > Code Coverage
3. Press "Select" next to "Included Assemblies"

Expected result: There is a way to see the full assembly name (horizontal scroll bar or the popup window can be resized)
Actual result: There is no way to see the full name of an assembly without resizing the whole Code Coverage window

Reproducible with: 2019.3.0f6, 2020.1.0a21
Could not test with: 2017.4.36f1 (no Package Manager), 2018.4.16f1, 2019.2.20f1 (no Code Coverage package)

Reproducible with package versions: 0.2.0-preview, 0.2.2-preview

Note: Make sure the Code Coverage window is small enough to see the problem
