OS: Windows 10 (x64) 
Chrome/Chromium version: 60.0.3112.90 ~ 55.0.2854

I have CTRL+T keystroke repeat issue in Chromium since many months. A new tab able to opens but I only pressed fourth time to CTRL+T. Likewise, CTRL+F (for find). Sometimes CTRL+W.

I'd changed the Keyboard response settings in the Windows Registry. Because of my keyboard response rate is very low. (You can research the keywords on Google for more detail info: increase repeat rate typing). 

I used the "FilterKeys Setter" called a tiny tool. It changed the FilterKeys Flag value to 3 from 126 (The Source code is also available):

What steps will reproduce the problem?

1) Increase to Keyboard response setting (a BATch file): https://paste.ee/r/IRUoU
2) Log-off and Log-on.
3) After run to Chromium, mouse pointer to click 4-5 times to the blank/white area on Most-visited pages). (Purpose: To not cursor focus override to omnibar.)
4) Press to CTRL+T.

Result: Chromium/Chrome will only be able to open a new tab, but only fourth pressed to CTRL+T.

If you've patience, you're use Chromium for a few hours or a day. During this time/day, in this way using will be tiresome. I've been living this persecution every but every day!

For now, there is two solution: 

a) Back to default the keyboard response settings: 

1) Default Keyboard response setting (a BATch file): https://paste.ee/r/bxznl
2-4) Repeat the above steps.

b) Disable FilterKeys: 

REGEDIT4
[HKEY_CURRENT_USER\Control Panel\Accessibility\Keyboard Response]
"Flags"="122"

Result: Directly pressed to CTRL+T. Chromium now opens a new tab at once.

This issue haven't happened in older versions (until to M53 or until to Build 416994. Meanwhile, Opera and Vivaldi's last builds haven't the issue).

I spent many hours and found out which revision/commit started the issue. I would like to ask you to revert the commit:
