.editor-styles-wrapper overriding my block styles in Gutenberg

This isn’t quite the solution I was looking for, but I realized that by making the tags more specific in the block stylesheets, I was able to prevent most issues from happening. By adding a div tag to the front of the tmp-container-fixed class, I was able to get the blocks to render properly in Gutenberg. (see below)

section.sign-up div.tmp-container-fixed {
    flex-direction: column;
}
