Unlabeled for screen readers buttons in some dialogs of Mp3tag

[k_kolev]

Hello,

In dialogs such as "Tag to filename", the button on the right of the drop-down combo-box is read by screen readers only as "4" ("four"), instead as with a label for its purpose as it should.

Steps to reproduce:

1. Launch a screen reader like NVDA or Narrator.
2. Launch Mp3tag.
3. Navigate to a directory of audio files containing tags.
4. Select one or more files in the list.
5. Invoke a dialog such as "Tag - Filename".
6. Use the TAB key to navigate/move the focus to the button for the variables, located on the right of the edit field (the one that has for a label only a triangle/arrow pointing to the right).
7. Observe how the screen reader will say only "4" ("four"), instead of a meaningful label for the button.

Actual result:
The screen reader will say only "4" ("four"), instead of a meaningful label for the button.

Expected result:
The screen reader should report a meaningful label for such buttons.

Test environment:

• Operating system: Windows 10 Pro version 1903 (build 18362.418), 64-bit, in Bulgarian with all locale settings set to "Bulgarian".
• Mp3tag version: 2.99a.

Thanks for reporting and the detailed description of the issue. I've reproduced it locally and will fix it with a future release of Mp3tag.

I've now fixed this with Mp3tag v2.99b.
