Query: Code Coverage Tab: how to force link original Cobertura ReportGenerator Report

[poojashahms]

In my pipeline, I have coverage.xml of cobertura style using reportgenerator
which has hyperlinks to visualize the missing coverage in actual code files.

Example:

Problem

When I enable diff coverage using CoveragePublisher and azurepipelines-coverage.yml file. I start seeing a different report which is not useful for my case because it doesn't have the navigation feature to the visuals.

In both the cases, I'm explicitly publishing at the end and also the right Html with index.html are produced properly (I can find them in the artifacts)
Expecting the same index.html to be linked on the Code Coverage tab. What am I missing? Because it works as expected without using CoveragePublisher (this repo's diff coverage)

Possible reason: I'm guessing somewhere call to https://github.com/microsoft/azure-pipelines-coveragepublisher/blob/master/src/CoveragePublisher/Publishers/DefaultPublisher/HtmlReportPublisher.cs is overriding the behavior.

How can I make the Code Coverage pick the index.html from the Code Coverage_Report folder?

Expected

1. Desire to get the ReporterGenerator report (as per the first screenshot) after enabling codeocveragepublsher's diff coverage comment on.

2. Also a query:
   In general, how doe the "Code Coverage" tab work? which file and which path it tries to look at? And what settings can change it's behaviour?

PS. With Visuals I mean, the highlights on actual code with what's not covered or covered. Example below are the screenshots I get on clicking on any of the classname in the first desired report.

Out of interest. How did you get the CodeCoverage tab filled with your html report files without using the "PublishCodeCoverageResults" task? Or where you using v1 of the task for your example at the top and then v2 for your example below?
