Cursor flashes as a block during Zsh startup

[smartinellimarco]

Hi! Just a small nitpick.
I've noticed that when Zsh is still loading, the cursor temporarily appears as a block before switching to a bar. This happens when using Powerlevel10k with Instant Prompt.

Here’s a video of it:

It would look super clean if the cursor was rendered as a bar beforehand, specially those times when zsh takes a bit more to load (i.e, when completions are recreated).

cursor-style = bar?
