Reduce vertical space before and after gb4e in footnote, align example with footnote text

Question

This is most definitely a follow-up question to Not excessively stretch vertical space between elements in gb4e (glossing verse text; issue w/ enumitem) and probably related to Adjust margins and interline spaces in gb4e.

My question is how to remove or reduce the copious amount of vertical space before and after an example in footnotes to what's normal in a footnote, as well as how to horizontally align the example block with the footnote text.

Note: I'm using enumitem, which apparently slightly complicates changing definitions in gb4e. The footmisc package may also place some obstacles.

Code:

\documentclass{article}

\usepackage{lipsum}
\usepackage{enumitem}
\usepackage[
    bottom,
    hang,
]{footmisc}
\usepackage{etoolbox}
\usepackage{gb4e}

Answer 1

A solution that worked for me in the end was wrapping the example in a minipage to \linewidth. This way, there is no excessive vertical space above the example, and it's indented relative to the footnote's text body. I put \\ after the minipage to create a little space under the environment, so the example would be slightly set off from the beginning of the next footnote, just as it would be in a block of text.
