Certain glyphs have a yellow box around them in code/.ipynb editor

[p-i-]

Type: Bug

I enter α β γ δ ε ᐯ ᐱ ᐳ ᐸ into a .ipynb

Now α γ ᐯ ᐳ ᐸ have a yellow box around them, whereas β δ ε ᐱ do not.

I've verified on https://unicode-explorer.com/tools/decode/ that there are no hidden unicode symbols.

Note that my FontFamily is Monaco, 'Apple Color Emoji'

How could β escape unscathed while its neighbours α and γ are each smitten?

PS I observe the problem ONLY in the code-editor and .ipynb editor. I've checked Terminal, DebugConsole, VariablesBrowser and Hover, and all are fine.

I believe this has to do with the editor.unicodeHighlight.ambiguousCharacters setting.
