'eval': not enough elements in tuple

[vbauerster]

Sometimes debug buffer is filled with following:

Looks like some InlayHints cannot be applied?

I'm using kak-lsp compiled from latest master.

error running command 'eval -buffer 'cmd.rs' -verbatim -- set buffer rust_analyzer_inlay_hints ...

strangely, running that command seems to work fine, so we're probably gonna need a reproducer.
I don't see anything wrong in the way we produce rust_analyzer_inlay_hints.

I did undo, which spawned multiple cursors which I didn't notice, then I entered insert mode and start typing without realizing that there were multiple cursors. FWIW this is a hint of what I was doing, not a reproducer.
