How can I increase line spacing in HTML footnote popups? CSS? JS?

The HTML Output’s footnotes and glossary popups have too tight of line spacing, but I can’t figure out where to adjust that. The top diacritics from one line overlap with the bottom diacritics from the line above.

In SAB I tried setting the line-height property to 200% or to 32 px for body.footnote, but that did not seem to have any effect in the HTML.

I tried poking around in the tooltipster.css file (used in the HTML output) and setting this line-height property there:

/* Use this next selector to style things like font-size and line-height: */
.tooltipster-default .tooltipster-content {
	font-family: Arial, sans-serif;
	font-size: 14px;
	line-height: 16px;
	padding: 8px 10px;
	overflow: hidden;

But that didn’t make any difference either. Maybe it’s getting overridden elsewhere?

You can see my HTML files here:

The footnote at the very end of this page is a nice long one on multiple lines.

Any idea what needs to be changed to increase the line spacing? Thanks!
