Timeline search results have text that cannot be selected

### Steps to reproduce

1. Starting from the timeline in the Element Web/Desktop room and have clicked the timeline search button
2. I click to focus in the search string box, type "test", and click the green magnifiying glass
3. I try to drag my pointer to select text in one of the search results and it behaves as if I've selected an image an offers to upload it when I release the mouse (Note that if I click on the search result it will exit the search results with that message selected such that I can now select the text in it, but at that point the rest of the search results are gone and I have to search again to then go back to search results.

### Outcome

#### What did you expect?

I expected to be able to select any visible text into my clipboard buffer.

#### What happened instead?

It tries to drag and drop an image of the text onto the channel when I release the mouse button. Some search results do have selectable text so this varies a bit as my video shows the first selection dragging an image, and the second two selecting text.
