Share options from external browsers fail in Android when Markor is not already open

⚠️ This issue respects the following points: ⚠️

• This is a bug. Not a question or feature request.
• The topic is not already reported at Issues. (I've searched it).
• Markor is up to date. See Releases for the latest version. Updates are available from F-Droid and GitHub.
• The bug is still present in the latest development version (git master). (Please download and try the test version of Markor, named Marder. Don't worry; Markor and Marder appear as completely separate applications. You can install both side-by-side, and Markor settings are not touched. In case the issue is resolved there, you don't need to create a bug report. The change will be part of the next Markor update.)

Description

The share options in both DuckDuckGo and Firefox browsers for Android fail unless Markor is already open. The failure is silent in DuckDuckGo, it results in an app crash report from Firefox 'Markor keeps stopping'.
Share options in some other apps work (it succeeds from the F-Droid app, but fails from my rss reader app).
If Markor is already open, it all works as would be expected.

Steps to reproduce

1. With Markor closed; open a web page in DuckDuckGo or Firefox on Android
2. Click on the app's share icon and select Markor
