InnerBlocks shows inline-image block, when not allowed

[hwinne]

Describe the bug
When a new block is inserted with the 'InnerBlock' component, and 'allowedBlocks' is used, the 'Inline-Image' block still shows, even when it's not allowed.

To Reproduce
Steps to reproduce the behaviour:

1. Go to the Gutenberg text-editor
2. Add a block which uses InnerBlocks (with specific blocks inside)
3. Add an InnerBlock
4. You can now see 'inline-image', even if it should not appear.
5. Save the post and reload the page, now the 'inline-image' option is gone.

Expected behaviour
The 'allowedBlocks' should appear, but if 'inline-image' is not allowed, it should not appear.

(Out of curiosity) how do you know when the inline images are and aren't supposed to appear. Is that something you see by reading the code or that you know from elsewhere? (Note: I don't know how to look that up in the code but would like to learn!)

I tested using the Media & Text block with WordPress 4.9.8 and Gutenberg 4.3 using Firefox 63.0.1 on macOS 10.13.6 and found that I was able to insert an inline image into an inner block (10s), however, now I am thinking that the following means that you are using custom code:

Are you able to provide a code example for how you've used allowedBlocks in your case?

[hwinne]

Yes it's when I build a custom block with InnerBlocks. I use allowedBlocks inside the edit function: <InnerBlocks allowedBlocks={ [ 'core/paragraph' ] }/> .
But when I use the insert block function it will also show the inline-image block:

This is only the first time when I insert the block. When I save the post and reload the page, the inline-image is gone:

Thanks for the reply. If you are able to provide a code example and tell me exactly where to place it (or maybe make a very small plugin that includes your custom block that can be installed for testing?), then I can help test. Otherwise, I've added the Needs Technical Feedback label and we can wait for a reply from someone with more developer experience to offer help.

I am not able to reproduce this issue on the current version of Gutenberg. So it seems fixed, as I have not seen other people having this issue. Therefore I will close this issue, thanks for your help anyway!
