This is not a bug per se, but it relates to the css of existing functionality and I thought it would get the attention it deserves in this section.
When the calendar is embedded in the site with the filter turned off,I noticed this extra space above the events. It would be nice to have this space automatically removed, tidying up the aesthetics when the toolbar is hidden.
If anyone else comes across this, Sunny shared this workaround for the time being though I have not verified it works yet:
"A workaround you can use that might help for now is to use custom css code to decrease the margin above the widget code where you embed the calendar, such as:
<div style="margin-top: -50px">
// widget embed code for your calendar
