Steps to reproduce:

1. Create a container with three lines of text and an UL list.
2. Style the container with "-webkit-box-orient: vertical" and "-webkit-line-clamp: 3"

Code Example:

Actual results:

The full text with the content of the ul list will be printed.

Expected results:

Only the first three lines should be printed.

This works the same way as Safari doesn't it?

It seems Chromium is recursing into nested non-anonymous blocks, which is rather odd. E.g., if I change the <ul> by a <div>, then Chrome agrees with us because the <div> is a nested flex container, but if I use another block like a <section>, then we disagree again. That's an slightly simpler test-case so will do that.

Only the first element is taken into account and the rest is totally ignored when it comes to display :block.
If elements are in display: inline or contents, no problem.
With inline-block, in this case, the property doesn't even work anymore.
