[BUGFIX] Linkbrowser fix

[gregordonsky]

A more robust approach that fixes item selection in linkbrowser.
This version will remove JavaScriptModuleInstruction xClass and just use only LinkBrowserController as xClass
ParentWindow is a new requireJS module which integrate only the getParent function in FormEngineLinkBrowserAdapter.
Compatible with typo3 9, 10, 11. Must be tested in v. 12.

LinkBrowserController is an xClass of ext:backend so you need to evaluate if the directory structure is correct or if you like having an xClass folder.

The file Configuration/Backend/Routes.php in the main branch should be used for all typo3 versions.

I think that this will definitely fix #509 #502 #451

I get inspired by the solution i found in FriendsOfTYPO3/frontend_editing#457 .
You can check it and FriendsOfTYPO3/frontend_editing#656 if you want to use a service instead of LinkBrowserController xclass.
In this case the code will be compatible only with typo3 version >= 11 because BootCompletedEventHandler is only defined by v.11

Ok, understand, but could you rework this patch a bit?

Do not delete the existing solution, as it works in TYPO3 v8 and yours only from TYPO3 v9 on.
So adding a version_compare() before XClassing and maybe. Would only take this for the 8.x branch and in the 11.x (main) branch adding the service variant.

Hi @opi99,

I don't remember very well, but I think I didn't mention v.8 because I haven't tested the code in typo3 v.8 environment.
I checked the typo3 v.8 source code and I think this patch should be compatible with this version as well.

Have you checked this in a typo3 v.8 environment? Unfortunately when I created this code I didn't have a v.8 to verify if everything was ok...

Closing in favor #528
