erp5_web_renderjs_ui: keep previous focus color

This reverts commit a87db49b.

Try to support displaying web js site from google cache,
which can not access original gadget, due to cross origin ajax query forbidden.

Display original content instead and load the default CSS in such case.

Most ERP5 web sites use a global form wrapping the content.
Modify the html viewer to not drop this content.
