Batch Count # not updating when manually changed - In Opera GX

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have custom nodes enabled

### What happened?

Short Report:
The Batch Count Number, I can highlight it, Delete it, Put it a new number, hit Enter on Keyboard. But the program won't register the 'Change' in Number.

The easiest way to test it:
Start up Comfyui, wait for URL page to open.
By Default, the Batch Count is 1, and the down Arrow is grayed out and unable to be clicked or interacted with.
Click on the 1, delete the number, put in a new number higher than 1, at least 2, hit the Enter Key.

^ If done right, the grayed out down arrow should change, no longer greyed out, and the up and down arrow should increment based on the number added. For 3, as an example, hitting up goes to 6, then 12, then 24.

Before I updated to latest everything, this was true and worked in Opera GX.
In Edge, found this was true and works.
After I updated everything, this is NOT true in Opera GX anymore.
Not sure if this Bug is just Opera GX, or all Chrome Browsers.

### Steps to Reproduce

1. Open Comfyui page in Opera GX
2. Click on the default Batch Count number, 1.
3. Delete the number
4. Put in a new number higher than 1, at least 2
5. Hit the Enter Key

### Additional Context

Full Report:

After going down a rabbit hole of figuring out what could be wrong, it was suggested I tried the program in a different browser. I opened Edge, pasted the local URL, and tried it. In Edge everything works, it updates the Batch Count like it should.

But my main browser I use is Opera GX, and it worked a few days ago before updating. Something must have broke somewhere for Opera GX specifically. I don't have any other browsers installed to test it tho.

The easiest way to test it:
Start up Comfyui, wait for URL page to open.
By Default, the Batch Count is 1, and the down Arrow is grey'd out and unable to be clicked or interacted with.
Click on the 1, delete the number, put in a new number higher than 1, at least 2, hit the Enter Key.

^ If done right, the grey'd out down arrow should change, no longer greyed out, and the up and down arrow should increment based on the number added. For 3, as an example, hitting up goes to 6, then 12, then 24.

In Edge, this was true and works.
Before I updated to latest everything, this was true and worked in Opera GX.
After I updated everything, this is NOT true in Opera GX anymore.

Even with CTRL + SHIFT + R to Hard Reset the page, this doesn't work. Opera GX just updated, in the middle of me typing this, that still didn't fix the issue. I deleted the 1, put in 3, hit enter, Button arrow still grey, when I hit the up arrow, it goes to 2, instead of 6, acting like I didn't change the Batch Count Number at all.

Opera GX Version: Lvl 7, Core: 129.0.5823.64

Start by reproducing the Batch Count edit steps in Opera GX and Edge, using frontend version 1.42.8 and the reported browser versions. Trace the Batch Count control from its frontend entry point and verify that pressing Enter updates the value and arrow behavior consistently in Opera GX without regressing Edge.
