International closing quotation marks are broken if surrounded by HTML Tags and punctuation marks

[apermo]

<!-- wp:paragraph -->
<p>lorem ipsum "<strong>text in correct quotation marks</strong>" dolor.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>lorem ipsum "<strong>text in broken quotation marks</strong>".</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>lorem ipsum "text in correct quotation marks".</p>
<!-- /wp:paragraph -->

Screenshot made using the snippet in WP 5.2.2 with latest twentynineteen, locale set to de_de.

I already discussed with @swisspidy and @tobifjellner on slack about it, and most likely it's a bug, the function replacing the normal " with the local opening or closing quotation marks has an issue as soon as html tags are next to them.
