convertPathData removes valid paths

[cyberalien]

Describe the bug
If path contains a 0 height shape, plugin removes that part of path.

To Reproduce
Steps to reproduce the behavior:

Example script:

import { optimize } from 'svgo';

const svg = optimize(
	`<svg xmlns="http://www.w3.org/2000/svg" version="1.1" viewBox="0 0 16 16" width="16" height="16" fill="none" stroke="currentColor" stroke-linecap="round" stroke-linejoin="round" stroke-width="1.5">
<path d="m8 5.25v0m0 6v-3.5"/>
</svg>`,
	{
		plugins: ['convertPathData'],
	}
);

console.log(svg.data);

Expected behavior
Expected path to contain first chunk with v0, but actual output is:

<svg xmlns="http://www.w3.org/2000/svg" version="1.1" viewBox="0 0 16 16" width="16" height="16" fill="none" stroke="currentColor" stroke-linecap="round" stroke-linejoin="round" stroke-width="1.5"><path d="M8 11.25v-3.5"/></svg>

Note that path contains only last chunk of original path, first chunk is gone, resulting in missing dot shape in icon.
