Bug 1545520 [wpt PR 16296] - Make list-and-block-textarea-001.html testing line-break only., a=testonly

Automatic update from web-platform-tests
Make list-and-block-textarea-001.html testing line-break only.

The purpose of list-and-block-textarea-001.html is to test line-break
between list marker and content. Separate the line-height issue to
another test case.
