Usability: use of custom parameters should not make entering dimensions harder

[lure23]

Setup:

- I have a design with e.g. "trackDiameter" (parameter name contains "m")

I want 'm' but Fusion 360 suggests a custom parameter

Steps:

- enter a dimension (e.g. "1m") and press Enter

Expected:

- the dimension should take effect, being 1 meter

Actual:

- Pressing Enter chooses a config value (e.g. "trackDiameter") instead, and "1trackDiameter" is not approved as a dimension

Work-around:

- Press Esc to hide the suggestion, then press Enter

This should be easy to fix, without changing the UI workflow. When Enter is pressed, and a suggestion is about to be selected, Fusion 360 could check whether the resulting metric ("1trackDiameter") is valid or not. This way entering "1 * m" + Enter would still pick the suggestion (as now), but for "1 m" + Enter the suggestion would not be applied.
