Hi @pmario I am concerned that the CSS selector here may trigger some false positives. The most obvious anomaly would be something like this:

<strong>
This is bold
<div style="font-weight:normal;">
This is not bold
<$link>
This should not be bold
<$/link>
</div>
</strong>

You are right. We need to be more specific. I had a look. We should add a new tc-emphasis tc-strong to the STRONG element created by the wikitext bold-parser.

The same should be true for: italic, strikethrough, subscript, subscript, superscript, underscore and inline-code

It seems to work fine now

<strong>
This is bold, 
<div style="font-weight:normal;">

This is not bold

<$link>This should not be bold</$link>

''<$link>This should be bold</$link>''

</div>
</strong>

//[[Internal link italics|example in italics]]// - It's italic also when the tiddler exists

''[[Internal link bold|example in bold]]'' - it's italic too, if tiddler does not exist
