Add note field to progress window

[abaevbog]

So one can add a child note to items that are being saved.

• if client passes canUserAddNote flag in ping response, display a textarea note field above tag selector
• the window will remain open if the focus is in the textarea, same as with tags
• on blur, note content is passed to the client to save as a child note
• Enter from the note field will add a new line. Shift-Enter can close the dialog.

The positioning of the textarea may need to be tweaked with a bit, especially with the tags autocomplete being added. We could only show the textarea if one presses a separate button, and keep it hidden otherwise - not sure.

This is good, but the textarea should either be more than 2 rows or auto-expand on focus/typing to at least 5 rows. Also your uploaded demo is inaccessible.

I figured that we don't want to make the textarea too big because the iframe is fairly small. I suppose not everyone would be regularly adding notes like this, so it's good to keep it as compact as possible. That said, 2 lines is indeed quite tight. First I tried to expand it to 5 lines on focus, same way we do it in editable-text with multiline fields in itembox. But it means that on blur, the field can potentially shrink, resize of the iframe, and potentially make one mis-click a component they were not aiming for. So maybe auto-expanding is the best solution here? Now, the field will expand to have the same height as the scrollHeight up to 6em, which fits 5 lines. On blur, it remains as is, without causing any resizing jumpiness.

Sorry about that! I must've not copied some path params in the url, which still worked fine for me cause I was logged in. I updated the link in the first comment.
