What it does

It fixes the fallback font-family in the monaco editor. Instead of falling back to the default UI font, which is

theia/packages/core/src/browser/style/variables-dark.useable.css

Line 40 in 1f0689e

--theia-ui-font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;

we fall back to the desired code editor font, which is

theia/packages/core/src/browser/style/variables-dark.useable.css

Line 52 in 1f0689e

--theia-code-font-family: Menlo, Monaco, Consolas, "Droid Sans Mono", "Courier New", monospace, "Droid Sans Fallback";

How to test

• Open the dev tools,
• select a view-lines element,
• and disable the default font-family.
