We use coverlet to generate code coverage reports in corefx.

Recently, I have observed an issue where opening up a report in Chrome and trying to navigate to to certain files/methods doesn't jump to the right anchor but rather just shifts the whole page down with blank space. This isn't doesn't exist on Edge (and navigation to a file/method work fine).
Steps to repro:
1) Clone corefx
2) Run build.cmd at root of the repo
3) Navigate to test project (say src\System.Text.Json\tests)
4) Run the following: dotnet msbuild /t:BuildAndTets /p:Coverage=true
5) Open up the generated report in <repo root>\artifacts\bin\System.Text.Json.Tests\netcoreapp-Debug\report\index.htm in Chrome and navigate to a file, say System.Text.Json_JsonDocument.htm.
6) Try clicking on one of the Files(s) or methods under the Metrics heading and observe the issue.

What end's up happening after clicking (a bunch of whitespace with the content pushed down):


Clicking the Methods/Properties on the side panels works fine.
The expectation is that the page jumps to the location of the file/method.
