The code mining "method parameter names" often leads to changing layout in the editor which is annoying when this happens while you are typing.

Consider the following code:

@Test
public void someTest() {
  assertEquals("some text", 2, List.of("x").size());
}

This is shown like below when the method parameter annotations are active:

@Test
public void someTest() {
  assertEquals(message: "some text", expected: 2, actual: List.of("x").size());
}


Now I want to change the "2" in the code above to "1".

- Place the cursor right of the "2"
- Delete the "2"

=> 

- First the editor changes to:

@Test
public void someTest() {
  assertEquals(message: "some text", , actual: List.of("x").size());
}

- Then (after maybe half a second) the editor changes to:


@Test
public void someTest() {
  assertEquals("some text", , List.of("x").size());
}

- Then I type "1" and the editor changes to

@Test
public void someTest() {
  assertEquals(message: "some text", expected: 1, actual: List.of("x").size());
}


This really is annoying - in particular when you look at a specific place in the editor to type something and suddenly the position changes. In the example above the cursor position changes 3 times.

What I want is:

@Test
public void someTest() {
  assertEquals(message: "some text", expected: 2, actual: List.of("x").size());
}


- Delete "2". Editor still shows all annotations:

@Test
public void someTest() {
  assertEquals(message: "some text", expected: , actual: List.of("x").size());
}

- Type "1". Editor still shows:

@Test
public void someTest() {
  assertEquals(message: "some text", expected: 1, actual: List.of("x").size());
}

=> Nothing jumps around, the user can always keep typing at the same screen position.
