Resolve "'Please select a file' when attempting to upload or replace from the UI"
What does this MR do?
- Disable Submit button while uploading file
- Hide file upload placeholder text if file exists
- vertically center place text
Are there points in the code the reviewer needs to double check?
- Should we show an overlay while uploading to make it clearer than just the progress bar?
- this should only affect file upload/replace on view blob page. Anywhere else is not intentional :)
