Hex Editor inherit font size from --vscode-font-size instead of editor.fontSize

[ruifengx]

The hex editor view inherits the font size from --vscode-font-size instead of editor.fontSize, so changing "editor.fontSize" in settings.json does not affect the font size for hex editor (while editing the value for vscode-font-size in workbench.desktop.main.js does the trick, but of course I don't want to mess up with files shipped with VSCode). Not sure if this is due to some misconfiguration on my side, or rather due to some design here.
