How to reproduce:
1. Create a new project
2. Import the Profile Analyzer package from the Package Manager
3. Open the Profile Analyzer window (Window -> Analysis -> Profile Analyzer)
4. In the Profile Analyzer window click the Compare tab and load the attached data (1.pdata and 2.pdata)
5. By clicking and dragging make a Frame Selection that has more frames than the other graph in total

Expected result: frame values should not exceed past their maximum values
Actual result: frame count and end frame values keep increasing past their maximum

Reproducible with: 0.4.0 - preview.5 (2018.4.20f1), 0.4.0 - preview.6 (2019.3.6f1), 0.5.0 - preview.1 (2020.1.0b2), 0.6.0 - preview.1 (2020.2.0a5)
Could not test with package versions: 0.4.0 - preview.3 (unable to load data)

Notes:
1. This issue does not occur when using keyboard commands (+, -, <, >) instead of dragging the selection
2. The frame count and end frame values are reverted to their correct values when the dragging is finished
