TYPO3 Core

Given:

• website with 2 languages (default and EN)
• Content Element of CType "ABC"
• ABC has a field of type inline (relation to table a)
• the foreign table has just a field of type input

1. create page
2. create content
3. translate page
4. translate content

1. modify content: add another item to the IRRE field
2. switch over to translated content element

now you see a "grayed out" IRRE item. Next to it a "localize"-button

ISSUE:

You hit the button "localize".

Wrong behaviour:

The grayed out item remains visible. Another item appears below.

Expected behaviour:

it should create a IRRE-element which replaces the "grayed out" item (as in TYPO3 v9).

Observed JavaScript Error in Browser Console:

InlineControlContainer.js?bust=1596661753:13 Uncaught (in promise) TypeError: t.compilerInput.localize is not iterable
    at VM1957 InlineControlContainer.js:13
