I hear you Kevin though again this is no different behavior compared
to earlier versions of Joomla such as 3.4.3 or J3.3.3 (I just
checked that as well) It shows exactly the same as on this link
http://gwsdev2.work/en/test22 also in previous versions. Also it
does show in the H1-tag as it should according to the documentation
<div class="item-page" itemscope="" itemtype="http://schema.org/Article">
<meta itemprop="inLanguage" content="en-GB">
<div class="page-header">
<h1> waters </h1>
</div>
I my example is "Blah" the article Title and "water" the by me given
value for Browser Page Title and your first message stated that the
error was that "it shows in the article" and for sure that is not
the fact me are pretty sure based on the code output and it behaves
according to the documentation me believe. If I am proven wrong than
I bow humbly for thou :) (and in that case you have discovered a
long time bug in Joomla since again check previous versions)
