CS1525 "Invalid expression term '/'" at wrong line when there is other comments prior to it

[Gnbrkm41]

Version Used:
Visual Studio 2017 Community 15.9.4 with ReSharper Ultimate 2018.2.3
Visual Studio 2019 16.0.0 Preview 1.1
Steps to Reproduce:

1. Type some comments (Can be either block comments or single-line comment)
2. Type some code with a single forward slash in front of it

Expected Behavior:
CS1525 "Invalid expression term '/'" error should be displayed at the line where the code with incomplete comment header is (i.e. division operator with nothing in front of it?)

Actual Behavior:

(Ignore the red squiggle on the right side, at line 33; that one's ReSharper's warning)

The warning is displayed at the end of the line prior to the comment.
