scrolling in a treetable using the mouse wheel leads to a "Uncaught (in promise) Error: "177.8" is of type number, expected int for property "firstVisibleRow" of Element "

[trashcoder]

What is the issue and how can we reproduce it?

Using Windows as OS with Microsoft Edge (Chrome) and setting up Mouse wheel behaviour to scroll a complete Page:

leads to the error.

Scrolling in a Table as Popup leads to a freeze. In the console you'll find this error message: Uncaught (in promise) Error: "177.8" is of type number, expected int for property "firstVisibleRow" of Element sap.ui.table.Table#

It's like this error: https://github.com/SAP/openui5/issues/2948

Changing it to scroll only several lines can be used as workaround.

Which OpenUI5 version is your project targeting?

1.110.2

Is the issue device- or browser-specific?

It's OS dependant

Not sure how to reproduce the error. Could you share an MRE as requested by https://github.com/SAP/openui5/issues/2948#issuecomment-654218836? The "Tip" mentioned in https://github.com/SAP/openui5/issues/new?template=1-bug-report.yml might help to create an MRE.

Also the OpenUI5 release version 1.110 has been out of maintenance since quite some time. Is the issue still reproducible with one of the maintained releases, e.g. with src="https://sdk.openui5.org/1.136/resources/sap-ui-core.js"?

Sorry, it's LTS version 1.108.30
