Tutorial: FancyButton.svelte not displayed as an editor tab

[akvadrako]

Describe the bug
Step https://svelte.dev/tutorial/dom-event-forwarding of the tutorial refers to a file called FancyButton.svelte. However this file is not displayed as an editor tab. If I try to create a new file with that exact name, it's displayed in red because the file already exists.

Logs
Nothing relevant in console.

Information about your Svelte project:

• Your browser and the version: Firefox 70.0b5
• Your operating system: Ubuntu Linux 19.10

Severity
It doesn't affect me much, but fixing it will make the tutorial more polished.

I can't reproduce this - the tab appears for me, on Firefox 73.

I have tried some things (clearing cache, FF 74.0b7, tracking protection) and it appears to be due to the AdblockPlus option "Block social media icons tracking".

When I disable it the tab appears. When it's enabled it says 0 items blocked, however looking at the ABP devtool tab I can see it blocks this element:

###FancyButton
Fanboy's Social Blocking List

This is a default list from ABP. So I guess it's up to you what to do about it - maybe renaming the file is worth it.

Huh. Yup I see that in https://github.com/easylist/easylist/blob/master/fanboy-addon/fanboy_social_general_hide.txt - I wonder what they're trying to block with that? Given how widely used Fanboy's list is, it probably makes sense to pick a different name.
