Broken <strong> after <em>

[zemlanin]

Describe the bug
Update to 1.0.0 broke the case of "emphasis, followed by punctuation, followed by strong" if both emphasis and strong are marked by asterisks

For example, *em*-**strong** in 0.8.2 correctly rendered <p><em>em</em>-<strong>strong</strong></p>, while 1.0.0 renders <p><em>em<em>-**strong</em></em></p>

To Reproduce
Steps to reproduce the behavior:

1. Marked Demo
2. CommonMark Demo

Expected behavior
*em*-**strong** should render <p><em>em</em>-<strong>strong</strong></p>

I believe this is fixed now by #1686
