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
Mounted folders change to unchecked after moving the session launcher page

To Reproduce

1. Go to 'Summary / Sessions' page
2. Click on 'Start' button to create a session
3. Mount some existing folders
4. Move to other pages of the session launcher by clicking the arrow buttons.

Expected behavior
Still checked.
