Description

Bug Description:

It looks like there is an event missing for codelens when the editor needs a refresh after a font change. When I change the font, the "RUN" | "Debug" command are missing over the main class in a JAVA project until I refresh (Just use the scroll button) to refresh the widget.

Steps to Reproduce:

1.Have JAVA dependencies available (JAVA pack + maven) in my configuration 2. git clone git@github.com:ryanluker/vscode-coverage-gutters.git ( Create a test environment) 3. Open a file in a JAVA project ( App.java) --> Observe the buttons: "Run " | "Debug" showing over the main class 4. Open the preference and change the "editor.fontSize": 22 5. Return to the JAVA file --> The "Run" | "Debug" buttons are not available until you scroll to refresh the widget

Contributor guide

Research direction
Investigate the codelens rendering logic and find where the font change event should trigger a refresh but is missing. Trace the event flow from font change to widget update.
