I've made a macro with 2 parameters: mm and inches. A user should be able to add this macro inline in a RTE, and then set a property on an ancestors node whether to use mm or inches.

Everything works fine when I first add the macro to the RTE. But after I've clicked save, Umbraco (tinyMCE?) splits the content of the RTE from:

<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p>

into this:

<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud </p>
<div class="umb-macro-holder mceNonEditable"><!-- <?UMBRACO_MACRO macroAlias="Length" lengthMm="12" lengthInches="21" /> --> <ins>Macro alias: <strong>Length</strong></ins></div>
<p> exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.<p>

That sucks. Because the macro is no longer inline.

Is there anyway to prevent this behaviour? I've tried to set forced_root_block to nothing in tinyMceConfig.config, but it doesnt solve the problem, since the content is still split up.
