can you share commands to reproduce the two issues?

Just run read (from both interactive and script) after setting fish_cursor_* in vi mode. For example (assuming default terminal cursor style is not line):

fish_vi_keybindings
set fish_cursor_insert line
read
fish -c read

For the first read, the cursor shape initially is not line (but changes once it switches out and then back to insert mode). For the second read (non interactive), the cursor shape doesn't change at all.
