`MO({AML})` is canceled by `AML_*` keys

[koron]

When set MO() with the layer which set as auto mouse layer, When holding the key then pressing AML_*, it turn off (disable) the layer.

MO(layer) - momentarily activates layer. As soon as you let go of the key, the layer is deactivated.

AML_* keys call set_auto_mouse_xxx() (where xxx is enable or timeout). set_auto_mouse_xxx() calls auto_mouse_reset(). auto_mouse_reset() clears the context's status and timer.

the cotext status is cleared, therefore no reasons to keep layer fo auto mouse ON. the layer will be off.

I dought auto_mouse_context.status.mouse_key_tracker

[koron]

I tried changing auto_mouse_reset() as follows. It keeps mouse_key_tracker beyond auto_mouse_reset().

Then this problem is fixed.

It is difficult to fix it with the Keyball alone. It requires modification of the QMK.

static void auto_mouse_reset(void) {
    int8_t tmp = auto_mouse_context.status.mouse_key_tracker;
    memset(&auto_mouse_context.status, 0, sizeof(auto_mouse_context.status));
    memset(&auto_mouse_context.timer, 0, sizeof(auto_mouse_context.timer));
    auto_mouse_context.status.mouse_key_tracker = tmp;
}
