Hi @lucasassisrosa, I noticed that I see an empty code snippet sometimes on first load/render. A reload seems to always correct the issue.

@sserrata I tried the following scenarios on the PR Preview and couldn't replicate the empty code snippet issue:

• landing on the page with no docusaurus.tab.code-samples language set then clicking on php tab
• landing on the page with docusaurus.tab.code-samples set to php

Could you share the scenario that uncovers the issue?

Maybe it's an issue with the localStorage docusaurus.tab.code-samples language that I cannot reproduce. Anyway, I added a piece of code to load code sample source from language on codeSampleCodeText initial state
