Diagram resizing on window resize requires reloading the page

[slauriere]

Steps to reproduce

1. Create a diagram
2. Add a rectangle to it, with a width of approximately 600 pixels
3. Save and view the diagram page
4. Resize the browser window so that the main column width gets inferior to the diagram rectangle size

Actual result

• The diagram area displays horizontal and vertical scrollbars (see capture below)
• When reloading the page, the diagram gets resized and the scrollbars disappear

Expected result

• The diagram gets resized dynamically without the need to reload the page

Environment

• Diagram Pro 1.15.5
• XWiki 13.0
• Firefox or Chrome

I couldn't reproduce this issue on MS Edge and Chrome, with local XWiki 13.0 (xwiki-platform-distribution-flavor-jetty-hsqldb) and app v.1.15.5 and the following newest versions due to the errors on the console tab (DT window).

After installing an extension and providing the name of the page - hit Create and loading freeze.

I do reproduce the issue on XWiki 15.10.10 Cloud Diagram Pro 1.20.5.
