@hvelarde I guess you mean the 12-old imported bug you refer to in the plone.app.layout #86 referred to by @rodfersou above. I wish the original bug was available but it seems it's no longer online.
But, apparently the actual beef of the said issue #86 was:
"folderish item with default page defined: base tag and URL must be the same (this is the actual issue here)"
Correct? What I do not understand is: why should that mean that the base href has to always be the same as the actual URL, also in views? As is now the case, after the change in 4.3.12.
In other words, before, the base href in say, editing view of any content (
/edit) was the URL of the context, ie. without the trailing
/edit. Made sense. Now, it's the URL of the view including the
/edit. The reason for issue #86 (quote above) said nothing of changing this or it the old behavior being a problem.
I am starting to wonder whether this is an undesired side-effect of #86 that we should file an issue for?
