Characters misplaced in inputted command

I have following terminal defined which has relatively long command:

{
  "name": "storybook here",
  "command": "npm run storybook:watch -- $(winpty -Xallow-non-tty -Xplain node C:/PROJECTS/foo/some-script.mjs \"[relativeFile]\")",
  "open": "true",
  "onlySingle": "true"
},

sometimes the command is being inputted into terminal with some of the characters placed in the wrong place. In this command in most cases it's the n in -Xplain missing but sometimes some other characters are getting missing as well. The strange thing is that they're not actually missing but are being placed somewhere later in the command. Resulting command always has the same length as the one that is not malformed, but there may be like 1, 2, maybe 3 characters that are in the wrong place. It probably depends on the length of the command and maybe on the length of the prompt since one of the characters that is getting misplaced is consistently the same one.

Dunno if that helps but this is an example of misplaced characters that actually happened to me today:

// proper command with irrelevant characters replaced with underscore, showing where are the ones that got misplaced:
$ __________________________________________________________n_________________________________p________________________________n___________________________________________________________________
// example 1: first "n" and "p" got misplaced
$ __________________________________________________________________________________________________np_________________________n___________________________________________________________________
// example 2: first "n" and "p" are ok but the second "n" is misplaced
$ __________________________________________________________n_________________________________p_______________________________________________________n____________________________________________

My terminal is a git bash on windows 10.
