FileUploader: prop "accept" is invalid.

[ggfer]

Describe the bug
set prop accept="png,jpg", but it doesn't work when files upload window pop up.

Code snippets

            <FileUploader className={classes.formDialogContentItemIcon}
              accept="png,jpg"
              disabled={false}
              hideInput={true}
              multiple={false}
              name={undefined}
              value={null}
              valueState="None"
              onChange={(e) => { onImageChange(e, data.id) }}
            >
              {data.icon ? <img className={classes.iconUpload} src={data.icon} /> : <Icon className={classes.iconUpload} name={"background"} tooltip="213123a" interactive={false} showTooltip={false} />}
            </FileUploader>

Expected behavior
file type excluded should have been disabled.

Screenshots

nothing is disabled.

Hey @ggfer,
thanks for reporting, I'll forward this issue to the UI5 Web Components Repo as the component is developed within that repository.

Hello @ggfer could you try adding the "." in front of the file extensions - accept=".png,.jpg".

Hey @ilhan007, I just added a PR (#2438) which adds the description as well, wasn't clear for me as well that .s are required.
