[BUG] sticky key in macro does not release

Bug:

When a macro that contains a sticky LSHIFT is run while other typing is happening, the release for the LSHIFT is either not read/ not sent, resulting in a stuck LSHIFT. Unplugging the kb does not release the key. This affects not only typing but the OS. The shift key is effectively always pressed.

To release the LSHIFT, you have to either

unplug the kb, reconnect, then rerun the same macro, and allow it to finish
run a macro containing &macro_release &kp LSHIFT

I'm connected via USB, if that makes a difference. I'm assuming that this will happen with other modifiers as well.

Config:

The quick-release must be enabled for sticky keys.
There needs to be one keypress before the sticky key in the macro.

&sk {
    release-after-ms = <1000>;
    quick-release;
};

ZMK_MACRO(test_sk,
        wait-ms = <20>;
        tap-ms = <20>;
        bindings = <&kp SPACE &sk LSHIFT>; 
    )
ZMK_MACRO(release_sk,
        wait-ms = <20>;
        tap-ms = <20>;
        bindings = <&macro_release &kp LSHIFT>;
    )

example typing behavior:

ststststst* sTSTSTSTSTS*tststststst start of sk macro **release macro
