Number of coach contents fixes

[MisRob]

Summary

This PR fixes case typos and also the problem with the info icon overlapping the progress bar that was caused by footerLength not being a number since the typo resulted in having undefined value in its calculation:

Before	After

After applying these fixes, as you can see on the "After" screenshot above, the resource title truncation doesn't work anymore again as expected (should truncate to 5 lines). I don't think that these updates are causing regression but rather reveal some new layout or styling conditions that also played role in #8667 and maybe @indirectlylit reported the issue under different conditions from when I tried to reproduce it. I'm reopening #8667 and will look into it again.
