ligatures do not work after square brace

[mikucionisaau]

I am trying to typeset expression [<=5], but the pair <= is not ligated after [, this pair is ligated fine after space or a number:

I do not experience this issue with other fonts (FiraCode, VictorMono).
The ligation also works fine after the parenthesis, curly braces, quotation marks -- everything seems consistent except after [.
So what is special about the square brace? Why the ligation does not work after [?

I guess it's F# attribute list brackets kicking in: [< and >]. They have ligatures for improved spacing between the chars.
@philippnurullin Is there some way to make operators like <= to have higher priority than these brackets?

[mikucionisaau]

Interesting, it is so subtle, that I can barely see ligation in [< :-)
Alternatively, maybe all three symbols could be ligated so everyone is happy?

Yes, i will add an exception for this case in on of the next updates.
