Browser fully crashes under macOS due to input element

[pbarry25]

Hi devs, appreciate y’all taking a look at the following.

Description of the issue:
Input element causes browser crash.

This just started with the most recent release. Similar issue filed with Chromium here.

Steps to Reproduce (add as many as necessary): 1. 2. 3.
(1) Create an HTML document with an input element of type file with accept="..json". See https://gist.github.com/TomSellers/4e27a513d645a02340ea9ca941a4640d

(2) Open the document

(3) click the input element

Actual Result (gifs and screenshots are welcome!):
Brave browser application crashes completely

Expected result:
Browser application does not crash

Reproduces how often:
100% of the time

Operating System and Brave Version(See the About Brave page in the main menu):
macOS 12.6.3, Brave Version 1.49.120 Chromium: 111.0.5563.64 (Official Build) (x86_64)

Additional Information:
Setting the value of accept to .json or .gz should not cause a crash (and did not, up until the latest build).

@pbarry25 thanks a bunch for reporting. Just to confirm, you’re also experiencing this with Chrome?

[pbarry25]

Hi Steeven!

Correct, I’m seeing this with both Chrome and Brave on macOS 12.6.3 (Intel platform).

Thanks!

@pbarry25,
Thanks for reaching out.
It looks like you’re correct and that this issue is due to a bug in the underlying Chromium engine. This will likely get resolved during the next Chromium bump — that said I will forward this information to our devs to review either way but yeah likely an upstream fix here.

Awesome, sounds good, Mattches. Big thanks to you and the Brave team for being so responsive to my post, really appreciate y’all!
