WYSIWYG Editor causing spurious issues with text - including deletion of random chunks

When using the WYSIWYG editor, there are observed critical issues:
– Lost chunks of text - usually related to the indent/bullet-point feature. This is the most pressing issue..
– "Strange" behavior of text - it puts a text box around random texts in the edit page; making it hard to "group select" chunks of text
– Loss of indentation, if indentation is used on paragraphs these are lost when saving. It should be noted they are still there when you copy-paste the text from the view layout.
– Similar to indentation, loss of spacing - put 4 spaces before the first word of a line, and it will render as 4 spaces when you save the first time. However, go to the edit view and the spaces before the first word are removed in the edit window, and if you save again spaces are removed from the view as well permanently thereafter
– "Strange" behavior of the bullet points - if you don't have a blank bullet at the end of a block of bullet points, the last one is usually removed.
