feature request: preventing existing hyperlinks from changed when page updated

Current status

When I use f command (Open a link in the current tab), I press the wrong keys sometimes. For example, press sv instead of sc.

At this point, if a page changes (e.g., js script), the original link of sc is changed to another one, like sf.

I think it is non-intuitive. Because my target is considered to remain as same as before I press the wrong key.

Suggestion

When a page changes,

• the original links must be the same, or deleted.
• the new links must be assigned to new mapping. (in the context of f command)

Real world example

I pressed f button, and my target is aj:

(link: https://www.google.com/search?q=vimium)

If I pressed sj, by mistake, some new DOM element shows up to the right side:

As you can see, now the aj change to sf.

p.s., I think, in some aspect, this can be regarded as a bug.

Start by tracing the f command's link-hint generation and how hints are reassigned when the page DOM changes. Reproduce the Google example by pressing f, triggering a page update, and checking whether existing hints retain their mappings. Done means existing links keep their mappings or are removed, while newly appearing links receive new mappings.
