What's in this Pull Request?

Fixing the issue when adding attachments to the ListAttachments control that contain one or more dots (".") in the name, the file type icon is not displayed (ex. PDF, Word, etc.)

Solution

To load the attachment preview in method loadAttachmentPreview we call GetFileImageUrl to fetch the previewImageUrl.

The old code is as below,

    const _fileTypes = _file.FileName.split('.');
    const _fileExtension = _fileTypes[1];

And since, the scenario when we have one or more dots (".") in the file name, the _fileExtension which will get the first element of array from _fileTypes

The corrected code is as below

const _fileExtension = _file.FileName.substr(_file.FileName.lastIndexOf('.') + 1);

this change will get the exact extension of the file.

below are the images from my local workbench.
