When a package name is escaped, IDEA code completion does not work as expected.

Note

This might seem like a corner issue, but as more and more domains are allocated, it is quite hard to find good names for open-source projects. I had to choose adaptive.fun for my project which implies that the package names start with fun.adaptive. Otherwise, I cannot upload to Maven Central and to Gradle plugin portal.

Test.kt (/declaration/src/commonMain/kotlin/hello world/a/b/Test.kt)

package `hello world`.a.b

class SomeClass()

To reproduce (see video):

1. open main.kt
2. position caret at <caret>
3. type some
4. hit Enter

fun main(<caret>) {
}

• the result is syntactically incorrect
• I would expect the short class name and an import

fun main(someClass: hello world.a.b.SomeClass) {
}

Note

Seems like this happens only when package name has to be escaped. For example, a simple hello does not produce this issue, even if escaped.
