Why does the font connection break with a multi-line header?

Question

css

Noticed this problem.
Example 1. Title of the publication: if it fits in one line - everything is OK, if there is more than one line, the following picture:

Example 2. In the block (list)

It can be seen that if there are more than one line, the font display is violated. Why can this be?

Answer 1

The problem is that the included font does not have Cyrillic! If this is a Google Font and this font has Cyrillic support, then connect it with Cyrillic and everything will be ok.
