bug when multiple use of item.html.twig

[finanalyst]

Data-Manager is a great plugin for developing.!!! But it fails if used too often.

Briefly my problem

• I have written two plugins, one customises the type list, called here var-dumper, the other customises the type details, called content-edit.
• However, when I enable var-dumper, which customises type list, the customised type detail for the other plugin disappears.
• Two types (using the terminology of DataManager) are involved.

In more detail

• I have reduced the files to the bare minimum that causes the problem, so only the Admin part is in each plugin.
• I include the pared-done php files, the data-manager twig files, and two data files in the expected format for each plugin.
• When var-dumper is not enabled, then the file in the data/content-edit directory is rendered as customised.
• When var-dumper is enabled, the same file is rendered by data-manager as if it is a non-customised *.yaml file.

Unless I have missed something, it seems there maybe a bug in data-manager when multiple non-standard datatypes are defined.

Update: If the priority on enabling the onPluginsInitialized is changed from 0 to 100, then this will affect which plugin over-rides which. I'm not sure which plugin comes first when both are on the same priority. But after editing var-dumper I had to increase its priority to 100, and then found that its items.html.twig was not being used.
