allImageSharp originalName regex not returning all images

[iamstevedavis]

Description

This is very similar to this issue here that was closed without resolution: #4843

I have a folder that has 4 images titled main_1.jpg, main_2.jpg, main_3.jpg and main_4.jpg. Using the following query, only three of the images are returned:

{
  allImageSharp(filter: {fluid: {originalName: {regex: "/^main.+/gm"}}}) {
    edges {
      node {
        id
        fluid {
          originalName
          originalImg
          src
          srcSet
        }
      }
    }
  }
}

Steps to reproduce

1. Create a folder with 4 or more images
2. Use the above query with a regex that will match all images in the folder
3. Run the query against graphql

Expected result

All images return.

Actual result

Only a subset of the images are returned.
