Current behavior

Line numbers are incorrect for template components. The tabs-headers only has 423 lines in it total.

Expected behavior

The line number should be somewhere below 423.

Minimal reproduction of the problem with instructions
I can reproduce this with a very simple template component with a failing test.

What is the motivation / use case for changing the behavior?

Will help debugging issues if the line numbers are correct.
