sectionChange falsely flagged as unknown attribute on ObjectPageLayout (sap.uxap)

[monika-palova]

The UI5 Language Assistant in VS Code flags sectionChange as an unknown attribute on uxap:ObjectPageLayout even though it's valid and works at runtime.

SAPUI5 version: 1.135.0
Library used: sap.uxap
Attribute: sectionChange (public since 1.73)

.ui5.yaml:

specVersion: "3.2"
type: library
framework:
    name: SAPUI5
    version: 1.135.0

Steps to reproduce:

<mvc:View
  xmlns:mvc="sap.ui.core.mvc"
  xmlns:uxap="sap.uxap"
  controllerName="...">

  <uxap:ObjectPageLayout
    id="opl"
    sectionChange="onSectionChange" />

</mvc:View>

UI5 Language Assistant version: 4.0.81

Dear @monika-palova
I have tried reproducing the issue you described but was unable to do so. I used the following project

sap.m.tutorial.walkthrough.20.zip
Additionally, here is a screenshot of the code that works without issues:

Could you please try using this project to see if you encounter the same issue? If the problem persists, it would be helpful if you could share a project that reliably reproduce the issue you're experiencing.

Thanks and best regards
