I've found two bugs in version 7, both when inserting links using the content editor:
1) Using both the admin-side and frontend publishing methods, additional <br> tags are added after the content. Sometimes it's two, sometimes three.
2) When using front-end editing/publishing, when you add a hyperlink in the content editor it adds a style="cursor: text;" on the anchor tag. (see screenshot for example).
Any fix for these in the works?
