Weird behavior for certain buttons

For the following code:
```
suspend fun main() = Korge() {

repeat(12) { //only happens for 12
text("Test")
}

val aText = text("")

uiButton(btnSize, btnSize) {
alignBottomToBottomOf(this@Korge, btnSize / 3)
alignLeftToLeftOf(this@Korge, btnSize / 3)
text = "test"
onClick {
aText.text = "Test"
}
}
uiButton(btnSize, btnSize) {
alignBottomToBottomOf(this@Korge, btnSize / 3)
alignRightToRightOf(this@Korge, btnSize / 3)
text = "test"
onClick {
aText.text = ""
}
}
}
```
clicking the button changes how the first button look

I tested this on Windows and Linux(arch with kde on x11) with jvm and js targets(Firefox and chromium), all with AMD graphics.

Start by reproducing the supplied suspend fun main Korge example with repeat(12), two uiButton calls, and clicks on both buttons. Compare the first button before and after updating aText across the reported JVM and JS targets. Done means clicking either button no longer changes the first button's appearance unexpectedly.
