Other browsers tested:
  Add OK or FAIL after other browsers where you have tested this issue:
     Safari: OK
    Firefox: OK
    IE/Edge: Didn't test

What steps will reproduce the problem?
1. Visit URL
2. Find in page for "tryserver_mail_test"

What is the expected result?
The string `'tests/tryserver_mail_test.py']` gets partially highlighted at the end of a long line near the top of the page.

What happens instead of that?
The correct line is highlighted, but the orange highlight is offset from the actual text on the page.

Please provide any additional information below. Attach a screenshot if
possible.

I was able to reproduce this with other strings than just the one at the end of the line. The incorrect offset seemed to be related to how far along inside the string it is.

Also tested on Chrome 'Version 70.0.3538.67 (Official Build) beta (64-bit)'. A coworker tested on mac osx and found the same bug.

Also reproduces in https://pastebin.com/9ZL4cnDu, which is a minimal version of the bug I think.
