[BUG] PDF Document Loader cannot upload files with a comma in the file name

[damirtresnjo]

I noticed an issue when you are running flowise locally on a windows 11 machine. You cannot upload a PDF file with commas in the file name into a PDF loader under Document Store.

To Reproduce Steps to reproduce the behavior:

1. Go to Document Stores
2. Add a store
3. Add a PDF loader
4. Click on upload a file
5. Select a file with a , in the file name (e.g. test,1.pdf)
6. No error, just no filename is selected

Setup

• Installation: npx flowise start
• Flowise Version: 2.2.6-hotfix.1
• OS: Windows 11
• Browser Chrome
