This (internal implementation) may be also related to a similar issue of v-autocomplete, where it isn't possible to change value without resetting input to immediately match the new value:

• [Bug Report] v-autocomplete doesn't allow changing value without changing search-input #12880

I've been also trying to implement a similar trim feature for a custom textbox component, but for now without successful completion, as there were still edge cases to be considered :(
Just for reference, I was progressing along these lines when brainstorming:

:value="
    currentInternalInput ===
    (trim ? valueAsText.trim() : valueAsText)
        ? currentInternalInput
        : valueAsText
"
@blur="
    // Normalize input on blur to match the bound value
    textRef.internalValue = trim ? valueAsText.trim() : valueAsText
"

And the same issue occurs if our use-case is a normalization numbers, e.g. 3.00 to 3.
