I was trying to correct a broken link in an old answer of mine on Stack Overflow, and really struggled until I realised that it was in Rich Text mode. (When did that happen? Not been very active on SO for a few weeks).
Problems encountered include:
Selecting the link text (multi-word) was in the first instance difficult, the edit link box appeared immediately obscuring the text I was trying to select so I could not see what I was selecting.
During the attempt to select the text the line-wrapping kept changing, presenting a moving target for the selection end-point.
On clicking the edit "pencil" icon, the link text box was pre-populated with a single (apparently random) word from the multi-word selection; not the whole selection.
Pasting in the URL and saving the change did not save the change, the URL remained unchanged.
Anyhow I switched to "Markdown with Preview" mode and now I am back in Kansas. Thankfully this selection appears to be persistent.
Interesting that this "feature" has not been applied to Meta (at time of writing).
Since this is supposed to be a question rather then simply an observation, is it just me?
