Change inside braces breaks intendation

Describe the bug
After using "change inside braces" ci{ command, the plugin deletes any indentation that the block of code had.

To Reproduce
Consider code such as this:

void main()
{
  printf("Hello world");
}

1. Put a cursor on word "printf"
2. Enter ci{ in normal mode
3. Watch everything including indentation removed from inbetween braces.

Expected behavior
Native vim deletes everything in-between curly braces, but leaves an indent upon entering insert mode

Screenshots
Initial code:

After ci{:

Expected (note the tabulation):

Additional context
The problem is particularly annoying in deeply nested {} blocks that have long indentation, as it removes all tabs within the block and I have to type them again every time after using ci{ command.

Reproduce the ci{ command in VS Code Vim using the C++ example from the issue, then trace the change-inside-braces command from its command entry point. Compare the result with native Vim and identify where indentation is removed. Done means ci{ preserves the existing indentation and a regression test covers the behavior.
