Github action preserve-block-position has incorrect default #395
Description
Describe the bug
Current logic adds --preserve-block-position to list of args if the length of the value provided to the preserve-block-position github actions variable is not zero. Since it defaults to the string false, this effectively defaults it to true. You can only disable it by setting it explicitly to an empty string.
Resolution
Fixed in #393
Additional context
Introduced in #351
