[FIX] web_editor: prevent inline content on blur

Avoid inlining the content of html_field during blur
to ensure we don't break edition.

Blur occurred when opening dynamic placeholder popup or media modal.

If, during those process, we inline the document content,
the Editor will lose the reference to the current caret position inside the document.
Because Elements where overridden or changed by the `toInline` function.

If the editor cannot put the caret back in the previous correct position,
it will put it back at the end of the document.
And thus inserting the dynamicPlaceholder or new media element
at the wrong place inside the document.
