[BUG] - released key is still considered pressed

[pau-not-paul]

Describe the bug
When typing a capital letter using shift (shift+letter), sometimes it registers the keydown event for the upper case letter but then it registers the keyup event for the lower case letter. Since it doesn't have a keyup event for the upper case letter, it thinks that it's still presses

How are you using react hotkeys components? (HotKeys, GlobalHotKeys, IgnoreKeys etc)
It happens in all the use cases.

Expected behavior
It should detect that the key has been released.

Platform (please complete the following information):
It happens with Chrome, Firefox, Safari...

Are you willing and able to create a PR request to fix this issue?
No, because I found a workaround:

configure({
  ignoreEventsCondition: (e) => {
    // This is a hack to solve an issue in react-hotkeys.
    // Sometimes it thinks that a letter is still pressed.
    // It happens when you type shift+letter and it registers
    // the keydown event of the letter as upper case, but it
    // registers the keyup event as lower case. Since there's
    // no keyup event for the upper case letter it thinks
    // that it's still pressed
    return !e.altKey && !e.ctrlKey && !e.metaKey && e.shiftKey;
  },
});

It happens with the default config.

The workaround doesn't seem to work for scenarios in which one is trying to capture both 'command+z' and 'command+shift+z':

• keydown 'command+z' -> triggers as expected
• releasing 'z' while continuing to hold 'command'
• keydown on 'shift' -> triggers 'command+shift+z' unexpectedly

Are you guys still having this problem? I was having an issue with nothing working after pressing spacebar and had to refocus the element to restore hotkey functionalities. I was using the package from npm.

I then cloned this repo locally and built it to figure out the issue and realized that the version on github is newer than the one in npm and the issue I was having wasn't present in this one. Maybe this had already been fixed but wasn't published?

I am experiencing the same bug as well. I was experimenting with my very first combinations command+z (undo), command+shit+z(redo) and it resulted exactly is what @mikhuang reported above.
