Currently the current selection is always requested as HTML by the
browser, and then we ask the browser to convert it to plain text.
The problem is that e.g. Writer can produce much better plain text from
its model, compared to the plain text by the browser, e.g. bullet
characters for bullet points.
Fix the problem by:
- CanvasTileLayer.js, _onTextSelectionMsg(): requesting both HTML and
plain text. Use ',' as a separator, as that's already established,
e.g. the HTTP Accept header does that already
- Switching the textselectioncontent protocol message from just HTML to
JSON that contains both HTML and plain text. This is produced in
ChildSession::getTextSelection() and parsed in CanvasTileLayer.js,
_onMessage()
- Clipboard.js, setTextSelectionHTML(): allowing setting both HTML and
plain text.
- ClientSession::postProcessCopyPayload(): knowing if the content to be
processed is HTML-in-JSON or just HTML, do additional escaping in the
JSON / textselectioncontent case, but leave the other clipboardcontent
case unchanged.
So far this only handles the simple case, the behavior for complex
selections are left unchanged for now. The payload is also unchanged
when a single format is requested, as many tests depend on test.
