vscode-coverage-gutters: Unable to get coverage to display

I can’t get coverage-gutters to render the gutters. After having done some tracing, I think the issue is in/around renderer.findIntersect(), as it always return “”.

Information about my setup:

• VS Code: 1.23.0 (OSX 10.13.4)
• Coverage Gutters: 2.0.0
• python: 2.7.14
• python coverage: 4.5.1
• pytest: 3.5.1
• pytest-cov: 2.5.1
• I’m generating cov.xml via pytest --cov=myprojectname --cov-report=xml:cov.xml

Snippet of cov.xml:

<coverage branch-rate="0" branches-covered="0" branches-valid="0" complexity="0" line-rate="0.7871" lines-covered="196" lines-valid="249" timestamp="1525805187668" version="4.5.1">

			<classes>
				<class branch-rate="0" complexity="0" filename="messages.py" line-rate="0.9691" name="messages.py">

						<line hits="1" number="5"/>
						<line hits="1" number="7"/>
					</lines>
				</class>
			</classes>
		</package>
	</packages>
</coverage>

For example, findTopSectionForEditor calls findIntersect(base: editorFile, comparee: sectionFile):

• editorFile: ###users###justfalter###code###myprojectname###myprojectname###messages.py
• sectionFile: messages.py

subInt ends up being messages.py, here: https://github.com/ryanluker/vscode-coverage-gutters/blob/f06458d0ae307118fe6ea54e2efa187dc6bc08e7/src/renderer.ts#L140

But the function always seems to return “” here: https://github.com/ryanluker/vscode-coverage-gutters/blob/f06458d0ae307118fe6ea54e2efa187dc6bc08e7/src/renderer.ts#L142-L144
