Clicking on a course sections in Teaching Loads page goes to the first section, not the one clicked

[kcarnold]

Describe the bug
On the Teaching Loads page, each of the sections looks clickable — it gets a pointer cursor; this got me thinking that they're links. But in fact only the whole table cell is clickable. Upshot: I click on one section (e.g., CS-375-B in the screenshot) and I get Update Section with the first section selected (in this case, INFO 602).

To Reproduce
Steps to reproduce the behavior:

1. Go to Teaching Loads
2. Click on a course section after a comma.
3. Notice that the Update Section modal shows the first section, not the one clicked.

Expected behavior
The Update Section modal starts with section 2 (or whatever it was) selected.

Additional context

• The sections could be <span> or even <a> elements.
• Ideally they would show meeting pattern location on mouseover.
