Describe the bug
Currently @duetds/date-picker does not work with Rollup (or I didn't get it to).
The problem appears to be a dynamic import statement with a template string:

return import(`./${bundleId}.entry.js${""}`);

Rollup seems to ignore these imports: "Dynamic imports on runtime are ignored by Rollup #2463"

**To

I'd be great if it were possible to set a placeholder content for the mathfield, equivalent to the placeholder-text of html-textareas. If this supported latex, it could easily be used to display text, too, by wrapping it in \text{...}.

Describe the bug
If the user inputs an invalid value to resource policy, the bottom border turns red but it can be updated.

To Reproduce

1. Go to 'Users' page (for admin)
2. Click on 'Resource Policy' tab
3. Update resource policy by clicking the setting icon button.
4. Input invalid value (higher than the maximum value)
5. See error

Expected behavior
Block updating.
