After upgrade of extension, content and borders of table are not shown anymore

[cdaecke]

Version(s) affected: 4.0.2, TYPO3 v11.5.34

Description
After upgrading the extension from v3.3.2 to v4.0.2 the content and cell borders of the table are not shown anymore. With version v3.3.2 I get the table like expected and shown in the screenshot below and in v4.0.2 I get just an empty table:

How to reproduce

• Install v3.3.2 of the extension and add the attached excel file
• Display frontend output -> It will show the table like expected and shown in the above screenshot
• Upgrade extension to v4.0.2, clear cache and display the frontend output again. It will display the empty table.

Possible Solution
Unfortunately I don't have a clue :-(

Additional context
No error messages are shown.

Having a deep dive into this issue, I found the following line, which fixed my problem:

spreadsheets/Classes/Service/ReaderService.php

Line 26 in 938c8d6

'xlsx' => (new Reader\Xlsx())->setReadEmptyCells(false)->load($reference->getForLocalProcessing()),

Old:
'xlsx' => (new Reader\Xlsx())->setReadEmptyCells(false)->load($reference->getForLocalProcessing()),

New
'xlsx' => (new Reader\Xlsx())->load($reference->getForLocalProcessing()),

Is this a known issue?
