Thanks for reporting, I confirm I can reproduce the problem.
Element Web and Element X iOS do not have the problem.

I have made some tests to see from which version this has regressed:

• https://github.com/element-hq/element-x-android/releases/tag/v0.6.4 OK
• https://github.com/element-hq/element-x-android/releases/tag/v0.6.5 KO

After a git bisect, the regression seems to come from this commit: 1e4c30c
