File chooser lacks access to app data

#### Describe the bug
I need to access certain files created by another app, in this case GPS tracks,
which I intend to send with Element. This used to be possible but after a recent
update (both of Element and LineageOS, can’t isolate which) the file choose
will no longer display the ``data`` directory.

The files are there without a doubt and the directory is accessible:

$ adb ls /sdcard/Android/data |wc -l
31
$ adb shell stat /sdcard/Android/data
File: /sdcard/Android/data
Size: 4096 Blocks: 16 IO Blocks: 512 directory
Device: 4bh/75d Inode: 245775 Links: 30 Device type: 0,0
Access: (0771/drwxrwx--x) Uid: ( 0/ root) Gid: ( 1015/sdcard_rw)
Access: 2021-01-05 23:23:26.480707969 +0100
Modify: 2021-06-14 01:23:19.044236329 +0200
Change: 2021-06-14 01:23:19.044236329 +0200

However in the file dialog all I see is this: https://i.imgur.com/wD39OYw.png
(“hidden files” are supposed to be shown).

#### To Reproduce

1. Open the send file dialog.
2. Navigate to ``/sdcard/Android/``.
3. The ``data`` subdirectory is not listed.

#### Expected behavior
The ``data`` dir should be shown and possible to enter, same for its
subdirectories. This used to work, I’ve been sending these files regularly in
the past.

#### Smartphone (please complete the following information):
- Device: [e.g. Samsung S6]
- OS: [e.g. Android 6.0]

#### Additional context
- Element v1.1.9 from F-Droid.
- LineageOS 18 with MicroG.
- Homeserver: ``matrix.org``.

Could this be a permissions error? Element has the “Allow access to media only”
perms set but not “Allowed to manage all files” like most other apps. I can’t
seem to find a way of fixing the permissions manually but then I’m not overly
familiar with Android.
