Bug report

Spreadsheet fromFile() method does not return reject promise when an error occurs while loading file. An error is thrown on the browser console instead.

The issue has been tracked to the following implementation in the source:

• In the spreadsheet/workbook.js, the method fromFile() rejects the promise only when no file has been passed to the method code
• In the spreadsheet/excel-reader.js the method readWorkbook() should receive the deferred object as its last argument, but is renamed to progress and never used in the method;

Reproduction of the problem

• On the following Dojo select invalid file in the file input (.png, .pdf, .jpg or other);

Expected:

the 'No file to be loaded!' should be alerted;

Actual:

An error will be thrown on the console

Kendo version: 2023.3.1010

I have the spreadsheet's first row and first column frozen.

I have also made the editor background red, so it is easier to visualize. 

Double click any cell below the frozen parts to enter editor mode, and you will see the editor drift out of its desired rectangle by 2 pixels,

 This is likely caused by the 2px border applied on the k-spreadsheet-pane
