I’m running into a weird issue with lightning:container and could really use your insights. βš™οΈ The Setup: I built an Aura component using lightning:container to embed an external app (index.html from a static resource). Everything works perfectly when only one instance is added to a record page. The Problem: When I add multiple instances of the same component: βœ… First Load: All instances render fine. πŸ” Page Refresh (F5 or Cmd+R): All lightning:container iframes fail to load β€” each one throws a:403 Forbidden: https://.../MatrixRuntime/index.html?...
βœ… Workaround: A hard refresh (empty cache + reload) fixes it temporarily β€” but obviously not ideal. πŸ§ͺ Code Snippet:

<div aura:id="exampleContainer" style="{!v.height ? 'height: ' + v.height + 'px;' : 'height:95%'}"> <lightning:container aura:id="exampleContainer1" src="{!$Resource.exampleContainer+ '/index.html'}" onmessage="{!c.handleMessageFromLightningContainer}" /> </div>

❓ Questions: Why does this only break on refresh (not initial load) with multiple instances? Could this be a known limitation or quirk of lightning:container? Appreciate any thoughts especially if you've hit this before πŸ™ Thanks in advance!
