Compose Web + kotlinx.serialization + Kotlin 1.7.10 JS IR with serializable typealias: "IllegalStateException: IdSignature clash"

[OliverO2]

Commit 5dc4f1d9d9d19505836cbe0250f1b7752aae6851 states:

Since kotlin 1.5.30, kotlinx.serialization plugin is forced to run its transformations before any other plugin. This made compose and kotlinx.serialization compatible, [...]

However, the following code fails to compile for JS IR. Replacing the typealias EventSequenceID by its underlying type Int makes it work.

Build script

plugins {
    kotlin("multiplatform") version "1.7.10"
    kotlin("plugin.serialization") version "1.7.10"
    id("org.jetbrains.compose") version "1.2.0-alpha01-dev745"
}

repositories {
    mavenCentral()
    maven("https://maven.pkg.jetbrains.space/public/p/compose/dev")
}

kotlin {
    js(IR) {
        browser()
    }

    sourceSets {
        val jsMain by getting {
            dependencies {
                implementation(compose.runtime)
                implementation("org.jetbrains.kotlinx:kotlinx-serialization-json:1.3.3")
            }
        }
    }
}

Code in JS source set

import kotlinx.serialization.Serializable

typealias EventSequenceID = Int

@Serializable
class Event(val sequenceID: EventSequenceID)

Previous issues were reporting an IdSignature clash, but under broader conditions (on every serializable class):

• #738
• #885
• https://github.com/Kotlin/kotlinx.serialization/issues/1454

The above cases did not reproduce with this issue's build environment, so I suppose these can be considered resolved.
