I just verified the issue for Tinymce 4.7.x is there in 4.8.x, 4.9.x and 5.0.0 making every "updated" tinymce version broken with editing "SPAN" inline. |

We found that most browser/tinymce bugs related to contenteditable are about editing non-DIV elements, so we try to change the template converter to always create an utility DIV and make it editable (Fix #429 and #362). This should still work with 4.5.x (currently the last version supported by mosaico) and by updated releases. Mosaico now supports multiple editing styles: the legacy styles are named "singleline" and "multiline" and they are automatically applied depending on the data-ko-editable element (td & div use "multiline", the other ones "singleline") but a data-ko-editor-style="newstyle" can be used to force the use of a different tinymce options set. This set will inherit ko.bindingHandlers.wysiwyg.standardOptions, ko.bindingHandlers.wysiwyg.fullOptions and then ko.bindingHandlers.wysiwyg.extendedOptions. (Fix #244) This changeset also remove the support for ko.bindingHandlers.wysiwyg.getContentOptions and replaces it with a new option "_use_raw_format" that defines wether to use "raw" format when getting/setting the content from tinymce. The new default is to use "raw" format for the singleline style and non raw format for everything else (the raw in singleline is required in order to prevent tinymce from trimming contents). Note that previously mosaico used raw format for every style, so if you want to preserve the previous behaviour you need to set ko.bindingHandlers.wysiwyg.fullOptions._use_raw_format to true. (should fix #446) Another breaking change is the default "extended_valid_elements" option that changed from "strong/b,em/i,*[*]" to "strong/b,em/i" so to enable content filtering and strip unwanted tags (like scripts). You can revert it by setting that option to the old value but beware XSS vulnerabilities. This changeset enable to upgrade of tinymce to newer 4.x (4.7.x, 4.9.x) and latest 5.x (Fix #593). For 5.x and 6.x we also had to update the scrollfix binding so that the toolbar is correclty moved when the edit area is scrolled. TinyMCE 6.x compatibility requires more changes because they removed support for "forced_root_block = false" or "forced_root_block = ''" that is needed for the singleline editing. You can trick tinymce by usign "forced_root_block = 'unknownelementname'" but it will prevent use of "ENTER" to insert <br/>. Issues #596 and #443 may be fixed by this changeset.

Using TinyMCE inline on SPANs give us unpredictable results.
See this fiddle:

So, we currently suggest to avoid Tinymce 4.7.x.
4.6.x seems to work, but sometimes we see an "Node cannot be null" exception (can't tell if this error creates issues or not).
4.5.x seems to work without exceptions.
