fix: standardize the copy html structure to avoid too many meaningles…

[boris-w]

…s dom node attributes.

When copying content in Firefox browser, the text/html content set will be transformed by the browser itself, causing meaningless node attributes on the DOM to be removed. Therefore, this PR standardizes the node attributes on the DOM, no longer separating the fieldVo attribute to set it on DOM node attributes, instead placing the entire fieldVo on the data-field attribute.

Error case:
write html

<table><thead id="fldxxxx" name="xxxx" type="text" isPrimary="true" ...><tr></tr></thead>...<table>

read html

<table><thead id="fldxxxx" name="xxxx" type="text"><tr></tr></thead>...<table>
