Do not fail to locate messages when a fragment directive has been appended. #31440
Description
My Use Case
What I Want To Achieve
Do not fail to locate messages included in the URI fragment, merely when a fragment directive has been appended, thereby allowing the browser to <mark> the content of text directives contained therein.
Why I Want To Achieve This
Although being able to hyperlink messages is useful, like develop.element.io/#/room/#foundation-office:matrix.org/$w_Qy0VgvRXswQWFPxHEOkPMV0xodm8VR6eQGf99SeTs, being able to link to specific sections thereof can be more important, when a long message is sent. However, if I append :~:text=hopefully%20the%20new%20rooms%20are%20more%20performant%20for%20you%2C%20and%20don't%20reset%20as%20often, to create develop.element.io/#/room/#foundation-office:matrix.org/$w_Qy0VgvRXswQWFPxHEOkPMV0xodm8VR6eQGf99SeTs:~:text=hopefully%20the%20new%20rooms%20are%20more%20performant%20for%20you%2C%20and%20don't%20reset%20as%20often, I see:

How I Want To Achieve This
Navigate to text directives manually appended to the URI fragment.
Considered Alternatives
Discard fragment directives, and render a banner that informs the user of this, if the fragment directive contained a text directive. 1 The banner should contain the included text, albeit sanitised.
Additional Context
I originally reported, at issues/31023#issuecomment-3616595234, that “Appending a fragment directive to the URI causes the viewport to move upward 50 %.” However:
We don't support this as a feature so I don't think that this is a bug. Feel free to open a separate feature request though.
Considering that, in those situations, the text directive is supported, I'm surprised.
That decision is why I haven't first reported not being able to navigate to linked-to messages as a bug. In its stead, I have included it as an aim of this enhancement request, but shall separate it if advised to.
