Bug: Photoshop online exports 0-byte files when filename has multiple periods

Issue: When exporting a file with multiple periods in the filename to my computer, the resulting file is 0 bytes. No error message is presented, but the green "Document Exported" banner also does not appear. An astute observer might realize something is wrong, but a new or unaware user would likely think the file was saved successfully until they go to open the file.  

• Photoshop version: Photoshop online. 
• OS: MacOS 15.2. Chrome Version 131.0.6778.265 (Official Build) (arm64). 

Steps to reproduce:

1. Open an image in Photoshop Online
2. Select "Main Menu> Export As..." and export the image to your local computer with the name: test.1.png
3. Inspect the file on your local computer and see the file size is 0 bytes.

Expected result: Exported files are downloaded to computers correctly with more than 0 bytes of data when using all valid filenames. If there is an issue, the user is presented with a warning or alert.
Actual result: Exported files have 0 bytes/no data when the filename has multiple periods. The user is not presented with any indications the file was not correctly exported.
