Game crashes with certain tags within tags

Game crashes when either referring to an inexistent tag, or a correct tag which is located in another data folder.

 

Example 1:

tag: "world/datapacks/name/data/name/tags/blocks/tag.json", shown below, contains an invalid tag:

{ "values": [ "minecraft:air", "#name:inexistant_tag" ] }

When opening a world with a datapack that this tag in it, the game will crash. Creating this tag while world is already opened and running the /reload command will return the following message: "An unexpected error occured trying to execute that command".

 

 

Example 2:

tag: "world/datapacks/name/data/name/tags/blocks/tag.json", shown below, contains a correct tag, which is located inside folder "world/datapacks/name/data/minecraft", rather than "world/datapacks/name/data/name":

{ "values": [ "minecraft:air", "#minecraft:logs" ] }

When opening a world with a datapack that this tag in it, the game will crash. Even though this is a correct tag and this did work in 1.13-pre4. Creating this tag while world is already opened and running the /reload command will return the following message: "An unexpected error occured trying to execute that command".
