Kernel crashes on <Shift-tab> while trying to access a method

[sbushmanov]

The kernel was installed by:

git clone https://github.com/almond-sh/almond
./mill dev.launcherFast 2.13.14
 out/scala/scala-kernel/2.13.14/unixFastLauncher.dest/launcher  --install --force --id scala213 --display-name "Scala (2.13.14)"

As the title says, while trying to access a method on an object like e.g.:

1.<press Shift-tab>

kernel dies:

Surprisingly, neither Scala 2.12 nor Scala 3 have this issue.
