How to reproduce:
1. Open user-submitted project (repro_634401)
2. While Unity is open, copy the contents of the 'New_Data' folder(located in root project folder) into the Assets/Data folder
3. Right-click the 'First' asset and 'Select Dependencies'

Expected result: 'Third' asset is among the dependencies for the 'First' asset
Actual result: 'Third' asset is not listed as a dependency for the 'First' asset

Reproducible with: 2018.3.11f1, 2019.1.0b9, 2019.2.0a10
Could not test with: 2017.4.24f1(TextAsset does not take 1 argument for its constructor)

Notes:
Reimporting the 'First' asset lists 'Third' as one of the dependencies correctly
