@vince-fugnitto - On analysis i found that this issue occurs for all the places (Like explorer tree context menu) and not only preference. Am able to reproduce this issue only in electron and not in browser.

I will raise a PR for fixing this by honouring zoom factor for electron context menu renderer.
