Description

Entries in the ToC can overflow if they are too long. This results in them being cut off.

See the bug live

Expected behaviour

Either

1. A scroll wheel appears
2. The name is cut-off with dots -> CommunityContentRouteHttp...

Option 2 feels the best from a UX standpoint IMO.

Actual behaviour

The name is cut-off after the maximum display width is reached, as can be seen in the above screenshots.
The full name is still visible when inspecting the HTML element.

Steps to reproduce

1. Give a class / method / attr a very long name
2. Look at the ToC entry
3. The ToC entry is cut-off

Thanks for reporting.

This problem is already solved in Insiders. The HTML needed some restructuring, to properly account for new features such as navigation icons, tooltips, and the upcoming navigation status badges. Backporting the new structure to the community edition would require significant effort. For this reason, I'd kindly ask you to use the following quick fix:

.md-nav__item .md-nav__link {
  display: block;
  width: 100%;
}

I'm afraid I can't really offer more at this point, except this fix or to switch to Insiders. However, the restructured HTML for navigation elements will be released together with navigation icons, which I'd expect to be some time next year.
