indent problem when declaring a type in jupyter lab

[thomasd3]

When you declare a type in Jupyter Lab, the auto-indent fails to put the bracket at the proper position.

I expect:

let a =
    {  <- indented

but it forcefully moves the cursor to the left and does:

let a = 
{ <- not indented

so every single type declaration has to be manually fixed AGAINST the auto-indent.
