Mailto: doesn't work in Chromium (SOLVED)

Hello,
it seems, that tag doesn’t work (tested with Chromium engine). It doesn’t open email client, but returns:
Error -302 when loading url mailto:xxx

Is any workaround or special way how to fix this?
Thanks a lot
Marty

Try

<a href="heexternal://mailto:xxx">

if it works.

Thanks a lot, this works well.
With best regards
Marty
